 <div class="block">FreeMarker MVC View servlet that can be used similarly to JSP views. That is, you put the variables to expose into
  HTTP servlet request attributes, then forward to an FTL file (instead of to a JSP file) that's mapped to this servet
  (usually via the <code>&lt;url-pattern&gt;*.ftl&lt;url-pattern&gt;</code>). See web.xml example (and more) in the FreeMarker Manual!


  <p>
  <b>Main features</b>
  </p>


  <ul>

  <li>It makes all request, request parameters, session, and servlet context attributes available to templates through
  <code>Request</code>, <code>RequestParameters</code>, <code>Session</code>, and <code>Application</code> variables.

  <li>The scope variables are also available via automatic scope discovery. That is, writing
  <code>Application.attrName</code>, <code>Session.attrName</code>, <code>Request.attrName</code> is not mandatory;
  it's enough to write <code>attrName</code>, and if no such variable was created in the template, it will search the
  variable in <code>Request</code>, and then in <code>Session</code>, and finally in <code>Application</code>.

  <li>It creates a variable with name <code>JspTaglibs</code> that can be used to load JSP taglibs. For example:<br>
  <code>&lt;#assign dt=JspTaglibs["http://displaytag.sf.net"]&gt;</code> or
  <code>&lt;#assign tiles=JspTaglibs["/WEB-INF/struts-tiles.tld"]&gt;</code>.

  <li>A custom directive named <code>include_page</code> allows you to include the output of another servlet resource from
  your servlet container, just as if you used <code>ServletRequest.getRequestDispatcher(path).include()</code>: <code>&lt;@include_page path="/myWebapp/somePage.jsp"/&gt;</code>. You can also pass parameters to the newly included page by passing a
  hash named <code>params</code>:
  <code>&lt;@include_page path="/myWebapp/somePage.jsp" params= lang: "en", q="5"}/&gt;</code>. By default, the request
  parameters of the original request (the one being processed by FreemarkerServlet) are also inherited by the include.
  You can explicitly control this inheritance using the <code>inherit_params</code> parameter:
  <code>&lt;@include_page path="/myWebapp/somePage.jsp" params={lang: "en", q="5"} inherit_params=false/&gt;</code>.

  </ul>


  <p>
  <b>Supported <code>init-param</code>-s</b>
  </p>


  <ul>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_TEMPLATE_PATH">"TemplatePath"</a></strong>: Specifies the location of the template files. By default,
  this is interpreted as a <code>ServletContext</code> resource path, which practically means a web application directory
  relative path, or a <code>WEB-INF/lib/*.jar/META-INF/resources</code>-relative path (note that this last haven't always
  worked before FreeMarker 2.3.23).<br>
  Alternatively, you can prepend it with <tt>file://</tt> to indicate a literal path in the file system (i.e.
  <tt>file:///var/www/project/templates/</tt>). Note that three slashes were used to specify an absolute path.<br>
  Also, you can prepend it with <code>classpath:</code>, like in <tt>classpath:com/example/templates</tt>, to indicate that
  you want to load templates from the specified package accessible through the Thread Context Class Loader of the
  thread that initializes this servlet.<br>
  If <code>incompatible_improvements</code> is set to 2.3.22 (or higher), you can specify multiple comma separated locations
  inside square brackets, like: <code>[ WEB-INF/templates, classpath:com/example/myapp/templates ]</code>. This internally
  creates a <a href="../../../freemarker/cache/MultiTemplateLoader.html" title="class in freemarker.cache"><code>MultiTemplateLoader</code></a>. Note again that if <code>incompatible_improvements</code> isn't set to at least
  2.3.22, the initial <code>[</code> has no special meaning, and so this feature is unavailable.<br>
  Any of the above can have a <code>?setting(name=value, ...)</code> postfix to set the JavaBeans properties of the
  <a href="../../../freemarker/cache/TemplateLoader.html" title="interface in freemarker.cache"><code>TemplateLoader</code></a> created. For example,
  <code>/templates?settings(attemptFileAccess=false, URLConnectionUsesCaches=true)</code> calls
  <a href="../../../freemarker/cache/WebappTemplateLoader.html#setAttemptFileAccess-boolean-"><code>WebappTemplateLoader.setAttemptFileAccess(boolean)</code></a> and
  <a href="../../../freemarker/cache/WebappTemplateLoader.html#setURLConnectionUsesCaches-java.lang.Boolean-"><code>WebappTemplateLoader.setURLConnectionUsesCaches(Boolean)</code></a> to tune the <a href="../../../freemarker/cache/WebappTemplateLoader.html" title="class in freemarker.cache"><code>WebappTemplateLoader</code></a>. For
  backward compatibility (not recommended!), you can use the <code>class://</code> prefix, like in
  <tt>class://com/example/templates</tt> format, which is similar to <code>classpath:</code>, except that it uses the
  defining class loader of this servlet's class. This can cause template-not-found errors, if that class (in
  <code>freemarer.jar</code> usually) is not local to the web application, while the templates are.<br>
  The default value is <tt>class://</tt> (that is, the root of the class hierarchy), which is not recommended anymore,
  and should be overwritten with the <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_TEMPLATE_PATH">"TemplatePath"</a> init-param.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_NO_CACHE">"NoCache"</a></strong>: If set to <code>true</code>, generates headers in the response that
  advise the HTTP client not to cache the returned page. If <code>false</code>, the HTTP response is not modified for this
  purpose. The default is <code>false</code>.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_CONTENT_TYPE">"ContentType"</a></strong>: The Content-type HTTP header value used in the HTTP responses
  when nothing else specifies the MIME type. The things that may specify the MIME type (and hence this init-param is
  ignored), starting with the highest precedence, are:
  <ol>
  <li>If the <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_OVERRIDE_RESPONSE_CONTENT_TYPE">"OverrideResponseContentType"</a> init-param is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_NEVER">"never"</a> (the
  default is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_ALWAYS">"always"</a>), then the value of <code>ServletResponse.getContentType()</code> is used
  if that's non-<code>null</code>.
  <li>The template's <tt>content_type</tt> custom attribute, usually specified via the <tt>attributes</tt> parameter of
  the <tt>&lt;#ftl&gt;</tt> directive. This is a legacy feature, deprecated by the <a href="../../../freemarker/core/OutputFormat.html" title="class in freemarker.core"><code>OutputFormat</code></a> mechanism.
  <li>The <a href="../../../freemarker/template/Template.html#getOutputFormat--">output format of the template</a>, if that has non-<code>null</code> MIME-type
  (<a href="../../../freemarker/core/OutputFormat.html#getMimeType--"><code>OutputFormat.getMimeType()</code></a>). When a template has no output format specified, <a href="../../../freemarker/core/UndefinedOutputFormat.html" title="class in freemarker.core"><code>UndefinedOutputFormat</code></a>
  is used, which has <code>null</code> MIME-type. (The output format of a template is deduced from <a href="../../../freemarker/template/Configuration.html" title="class in freemarker.template"><code>Configuration</code></a>
  settings, or can be specified directly in the template, like <code>&lt;#ftl outputFormat="HTML"&gt;</code>. See the FreeMarker
  Manual for more about the output format mechanism. Note that setting an output format may turns on auto-escaping, so
  it's not just about MIME types.)
  <li>If the <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_OVERRIDE_RESPONSE_CONTENT_TYPE">"OverrideResponseContentType"</a> init-param is not <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_ALWAYS">"always"</a>
  (the default is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_ALWAYS">"always"</a>), then the value of <code>ServletResponse.getContentType()</code> is
  used if that's non-<code>null</code>.
  </ol>
  If none of the above gives a MIME type, then this init-param does. Defaults to <tt>"text/html"</tt>. If and only if
  the <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_RESPONSE_CHARACTER_ENCODING">"ResponseCharacterEncoding"</a> init-param is set to <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_LEGACY">"legacy"</a> (which is
  the default of it), the content type may include the charset (as in <tt>"text/html; charset=utf-8"</tt>), in which
  case that specifies the actual charset of the output. If the the <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_RESPONSE_CHARACTER_ENCODING">"ResponseCharacterEncoding"</a>
  init-param is not set to <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_LEGACY">"legacy"</a>, then specifying the charset in the
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_CONTENT_TYPE">"ContentType"</a> init-param is not allowed, and will cause servlet initialization error.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_OVERRIDE_RESPONSE_CONTENT_TYPE">"OverrideResponseContentType"</a></strong> (since 2.3.24): Specifies when we should
  override the <code>contentType</code> that might be already set (i.e., non-<code>null</code>) in the
  <code>HttpServletResponse</code>. The default is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_ALWAYS">"always"</a>, which means that we always set the
  content type. Another possible value is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_NEVER">"never"</a>, which means that we don't set the content
  type in the response, unless <code>ServletResponse.getContentType()</code> is <code>null</code>. The third possible value
  is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_WHEN_TEMPLATE_HAS_MIME_TYPE">"whenTemplateHasMimeType"</a>, which means that we only set the content type if either
  the template has an associated <a href="../../../freemarker/core/OutputFormat.html" title="class in freemarker.core"><code>OutputFormat</code></a> with non-<code>null</code> <a href="../../../freemarker/core/OutputFormat.html#getMimeType--"><code>OutputFormat.getMimeType()</code></a>, or it
  has a custom attribute with name <tt>content_type</tt>, or <code>ServletResponse.getContentType()</code> is
  <code>null</code>. Setting this init-param allows you to specify the content type before forwarding to
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html" title="class in freemarker.ext.servlet"><code>FreemarkerServlet</code></a>.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_OVERRIDE_RESPONSE_LOCALE">"OverrideResponseLocale"</a></strong> (since 2.3.24): Specifies if we should override
  the template <code>locale</code> that might be already set (i.e., non-<code>null</code>) in the <code>HttpServletRequest</code>. The
  default is <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_ALWAYS">"always"</a>, which means that we always deduce the template <code>locale</code> by
  invoking <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#deduceLocale-java.lang.String-javax.servlet.http.HttpServletRequest-javax.servlet.http.HttpServletResponse-"><code>deduceLocale(String, HttpServletRequest, HttpServletResponse)</code></a>. Another possible value is
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_NEVER">"never"</a>, which means that we don't deduce the template <code>locale</code>, unless
  <code>ServletRequest.getLocale()</code> is <code>null</code>.

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_RESPONSE_CHARACTER_ENCODING">"ResponseCharacterEncoding"</a></strong> (since 2.3.24): Specifies how the
  <code>HttpServletResponse</code> "character encoding" (as in <code>ServletResponse.setCharacterEncoding(String)</code>)
  will be deduced. The possible modes are:
  <ul>
  <li><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_LEGACY">"legacy"</a>: This is the default for backward compatibility; in new applications, use
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_FROM_TEMPLATE">"fromTemplate"</a> (or some of the other options) instead. <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_LEGACY">"legacy"</a>
  will use the charset of the template file to set the charset of the servlet response. Except, if the
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_CONTENT_TYPE">"ContentType"</a> init-param contains a charset, it will use that instead. A quirk of this legacy
  mode is that it's not aware of the <a href="../../../freemarker/core/Configurable.html#getOutputEncoding--"><code>Configurable.getOutputEncoding()</code></a> FreeMarker setting, and thus never reads
  or writes it (though very few applications utilize that setting anyway). Also, it sets the charset of the servlet
  response by adding it to the response content type via calling <code>ServletResponse.setContentType(String)</code> (as
  that was the only way before Servlet 2.4), not via the more modern
  <code>ServletResponse.setCharacterEncoding(String)</code> method. Note that the charset of a template usually comes
  from <a href="../../../freemarker/template/Configuration.html#getDefaultEncoding--"><code>Configuration.getDefaultEncoding()</code></a> (i.e., from the <code>default_encoding</code> FreeMarker setting),
  occasionally from <a href="../../../freemarker/template/Configuration.html#getEncoding-java.util.Locale-"><code>Configuration.getEncoding(Locale)</code></a> (when FreeMarker was configured to use different charsets
  depending on the locale) or even more rarely from <a href="../../../freemarker/template/Configuration.html#getTemplateConfigurations--"><code>Configuration.getTemplateConfigurations()</code></a> (when FreeMarker was
  configured to use a specific charset for certain templates).
  <li><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_FROM_TEMPLATE">"fromTemplate"</a>: This should be used in most applications, but it's not the default for
  backward compatibility. It reads the <a href="../../../freemarker/core/Configurable.html#getOutputEncoding--"><code>Configurable.getOutputEncoding()</code></a> setting of the template (note that the
  template usually just inherits that from the <a href="../../../freemarker/template/Configuration.html" title="class in freemarker.template"><code>Configuration</code></a>), and if that's not set, then reads the source
  charset of the template, just like <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_LEGACY">"legacy"</a>. Then it passes the charset acquired this way to
  <code>ServletResponse.setCharacterEncoding(String)</code> and <a href="../../../freemarker/core/Environment.html#setOutputEncoding-java.lang.String-"><code>Environment.setOutputEncoding(String)</code></a>. (It
  doesn't call the legacy <code>ServletResponse.setContentType(String)</code> API to set the charset.) (Note that if the
  template has a <code>content_type</code> template attribute (which is deprecated) that specifies a charset, it will be
  used as the output charset of that template.)
  <li><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_DO_NOT_SET">"doNotSet"</a>: <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html" title="class in freemarker.ext.servlet"><code>FreemarkerServlet</code></a> will not set the <code>HttpServletResponse</code>
  "character encoding". It will still call <a href="../../../freemarker/core/Environment.html#setOutputEncoding-java.lang.String-"><code>Environment.setOutputEncoding(String)</code></a>, so that the running template
  will be aware of the charset used for the output.
  <li><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_VALUE_FORCE_PREFIX">"force "</a> + charset name, for example <code>force UTF-8</code>: The output charset will
  be the one specified after "force" + space, regardless of everything. The charset specified this way is passed to
  <code>ServletResponse.setCharacterEncoding(String)</code> and <a href="../../../freemarker/core/Environment.html#setOutputEncoding-java.lang.String-"><code>Environment.setOutputEncoding(String)</code></a>. If the
  charset name is not recognized by Java, the servlet initialization will fail.
  </ul>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_BUFFER_SIZE">"BufferSize"</a></strong>: Sets the size of the output buffer in bytes, or if "KB" or
  "MB" is written after the number (like <code>&lt;param-value&gt;256 KB&lt;/param-value&gt;</code>) then in kilobytes or megabytes.
  This corresponds to <code>ServletResponse.setBufferSize(int)</code>. If the <code>HttpServletResponse</code> state doesn't
  allow changing the buffer size, it will silently do nothing. If this init param isn't specified, then the buffer size
  is not set by <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html" title="class in freemarker.ext.servlet"><code>FreemarkerServlet</code></a> in the HTTP response, which usually means that the default buffer size of the
  servlet container will be used.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_EXCEPTION_ON_MISSING_TEMPLATE">"ExceptionOnMissingTemplate"</a></strong> (since 2.3.22): If <code>false</code> (default,
  but not recommended), if a template is requested that's missing, this servlet responses with a HTTP 404 "Not found"
  error, and only logs the problem with debug level. If <code>true</code> (recommended), the servlet will log the issue with
  error level, then throws an exception that bubbles up to the servlet container, which usually then creates a HTTP 500
  "Internal server error" response (and maybe logs the event into the container log). See "Error handling" later for
  more!</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_META_INF_TLD_LOCATIONS">"MetaInfTldSources"</a></strong> (since 2.3.22): Comma separated list of items, each
  is either <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#META_INF_TLD_LOCATION_WEB_INF_PER_LIB_JARS">"webInfPerLibJars"</a>, or <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#META_INF_TLD_LOCATION_CLASSPATH">"classpath"</a>
  optionally followed by colon and a regular expression, or <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#META_INF_TLD_LOCATION_CLEAR">"clear"</a>. For example <code>&lt;param-value&gt;classpath:.*myoverride.*\.jar$, webInfPerLibJars, classpath:.*taglib.*\.jar$&lt;/param-value&gt;</code>, or <code>&lt;param-value&gt;classpath&lt;/param-value&gt;</code>. (Whitespace around the commas and list items will be ignored.) See
  <a href="../../../freemarker/ext/jsp/TaglibFactory.html#setMetaInfTldSources-java.util.List-"><code>TaglibFactory.setMetaInfTldSources(List)</code></a> for more information. Defaults to a list that contains
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#META_INF_TLD_LOCATION_WEB_INF_PER_LIB_JARS">"webInfPerLibJars"</a> only (can be overridden with
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#createDefaultMetaInfTldSources--"><code>createDefaultMetaInfTldSources()</code></a>). Note that this can be also specified with the
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#SYSTEM_PROPERTY_META_INF_TLD_SOURCES">"org.freemarker.jsp.metaInfTldSources"</a> system property. If both the init-param and the system property
  exists, the sources listed in the system property will be added after those specified by the init-param. This is
  where the special entry, <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#META_INF_TLD_LOCATION_CLEAR">"clear"</a> comes handy, as it will remove all previous list
  items. (An intended usage of the system property is setting it to <code>clear, classpath</code> in the Eclipse run
  configuration if you are running the application without putting the dependency jar-s into <code>WEB-INF/lib</code>.)
  Also, note that further <code>classpath:&lt;pattern&gt;</code> items are added automatically at the end of this list based on
  Jetty's <code>"org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern"</code> servlet context attribute.</li>

  <li><strong><a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_CLASSPATH_TLDS">"ClasspathTlds"</a></strong> (since 2.3.22): Comma separated list of paths; see
  <a href="../../../freemarker/ext/jsp/TaglibFactory.html#setClasspathTlds-java.util.List-"><code>TaglibFactory.setClasspathTlds(List)</code></a>. Whitespace around the list items will be ignored. Defaults to no paths
  (can be overidden with <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#createDefaultClassPathTlds--"><code>createDefaultClassPathTlds()</code></a>). Note that this can also be specified with the
  <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#SYSTEM_PROPERTY_CLASSPATH_TLDS">"org.freemarker.jsp.classpathTlds"</a> system property. If both the init-param and the system property exists, the
  items listed in system property will be added after those specified by the init-param.</li>

  <li><strong>"Debug"</strong>: Deprecated, has no effect since 2.3.22. (Earlier it has enabled/disabled sending
  debug-level log messages to the servlet container log, but this servlet doesn't log debug level messages into the
  servlet container log anymore, only into the FreeMarker log.)</li>

  <li>The following init-params are supported only for backward compatibility, and their usage is discouraged:
  <code>TemplateUpdateInterval</code>, <code>DefaultEncoding</code>, <code>ObjectWrapper</code>, <code>TemplateExceptionHandler</code>.
  Instead, use init-params with the setting names documented at <a href="../../../freemarker/template/Configuration.html#setSetting-java.lang.String-java.lang.String-"><code>Configuration.setSetting(String, String)</code></a>, such
  as <code>object_wrapper</code>.

  <li><strong>Any other init-params</strong> will be interpreted as <a href="../../../freemarker/template/Configuration.html" title="class in freemarker.template"><code>Configuration</code></a>-level FreeMarker setting. See
  the possible names and values at <a href="../../../freemarker/template/Configuration.html#setSetting-java.lang.String-java.lang.String-"><code>Configuration.setSetting(String, String)</code></a>. Note that these init-param names
  are starting with lower-case letter (upper-case init-params are used for FreemarkerSerlvet settings).</li>

  </ul>


  <p>
  <b>Error handling</b>
  </p>


  <p>
  Notes:
  </p>

  <ul>

  <li>Logging below, where not said otherwise, always refers to logging with FreeMarker's logging facility (see
  <a href="../../../freemarker/log/Logger.html" title="class in freemarker.log"><code>Logger</code></a>), under the "freemarker.servlet" category.</li>
  <li>Throwing a <code>ServletException</code> to the servlet container is mentioned at a few places below. That in practice
  usually means HTTP 500 "Internal server error" response, and maybe a log entry in the servlet container's log.</li>
  </ul>

  <p>
  Errors types:
  </p>

  <ul>

  <li>If the servlet initialization fails, the servlet won't be started as usual. The cause is usually logged with
  error level. When it isn't, check the servlet container's log.

  <li>If the requested template doesn't exist, by default the servlet returns a HTTP 404 "Not found" response, and logs
  the problem with <em>debug</em> level. Responding with HTTP 404 is how JSP behaves, but it's actually not a
  recommended setting anymore. By setting <a href="../../../freemarker/ext/servlet/FreemarkerServlet.html#INIT_PARAM_EXCEPTION_ON_MISSING_TEMPLATE">"ExceptionOnMissingTemplate"</a> init-param to <code>true</code>
  (recommended), it will instead log the problem with error level, then the servlet throws <code>ServletException</code> to
  the servlet container (with the proper cause exception). After all, if the visited URL had an associated "action" but
  the template behind it is missing, that's an internal server error, not a wrong URL.</li>

  <li>If the template contains parsing errors, it will log it with error level, then the servlet throws
  <code>ServletException</code> to the servlet container (with the proper cause exception).</li>

  <li>If the template throws exception during its execution, and the value of the <code>template_exception_handler</code>
  init-param is <code>rethrow</code> (recommended), it will log it with error level and then the servlet throws
  <code>ServletException</code> to the servlet container (with the proper cause exception). But beware, the default value of
  the <code>template_exception_handler</code> init-param is <code>html_debug</code>, which is for development only! Set it to
  <code>rethrow</code> for production. The <code>html_debug</code> (and <code>debug</code>) handlers will print error details to the
  page and then commit the HTTP response with response code 200 "OK", thus, the server wont be able roll back the
  response and send back an HTTP 500 page. This is so that the template developers will see the error without digging
  the logs.
