+  This is the authentication configuration file for protocol-httpclient.
+  Different credentials for different authentication scopes can be
+  configured in this file. If a set of credentials is configured for a 
+  particular authentication scope (i.e. particular host, port number,
+  scheme and realm), then that set of credentials would be sent only to
+  servers falling under the specified authentication scope. Apart from
+  this at most one set of credentials can be configured as 'default'.
+  
+  When authentication is required to fetch a resource from a web-server,
+  the authentication-scope is determined from the host, port, scheme and
+  realm (if present) obtained from the URL of the page and the
+  authentication headers in the HTTP response. If it matches any
+  'authscope' in this configuration file, then the 'credentials' for
+  that 'authscope' is used for authentication. Otherwise, it would use
+  the 'default' set of credentials (with an exception which is described
+  in the next paragraph), if present. If any attribute is missing, it
+  would match all values for that attribute.
+
+  If there are several pages having different authentication realms and
+  schemes on the same web-server (same host and port, but different
+  realms and schemes), and credentials for one or more of the realms and
+  schemes for that web-server is specified, then the 'default'
+  credentials would be ignored completely for that web-server (for that
+  host and port). So, credentials to handle all realms and schemes for
+  that server may be specified explicitly by adding an extra 'authscope'
+  tag with the 'realm' and 'scheme' attributes missing for that server.
+  This is demonstrated by the last 'authscope' tag for 'example:8080' in
+  the following example.
+
+  Example:-
+    <credentials username="susam" password="masus">
+      <default realm="sso"/>
+      <authscope host="192.168.101.33" port="80" realm="login"/>
+      <authscope host="example" port="8080" realm="blogs"/>
+      <authscope host="example" port="8080" realm="wiki"/>
+      <authscope host="example" port="80" realm="quiz" scheme="NTLM"/>
+    </credentials>
+    <credentials username="admin" password="nimda">
+      <authscope host="example" port="8080"/>
+    </credentials>
+
+  In the above example, 'example:8080' server has pages with multiple
+  authentication realms. The first set of credentials would be used for
+  'blogs' and 'wiki' authentication realms. The second set of
+  credentials would be used for all other realms. For 'login' realm of
+  '192.168.101.33', the first set of credentials would be used. For any
+  other realm of '192.168.101.33' authentication would not be done. For
+  the NTLM authentication required by 'example:80', the first set of
+  credentials would be used. For 'sso' realms of all other servers, the
+  first set of credentials would be used, since it is configured as
+  'default'.
+
+  NTLM does not use the notion of realms. The domain name may be
+  specified as the value for 'realm' attribute in case of NTLM.
+
+ More information on Basic, Digest and NTLM authentication
+ support can be located at https://wiki.apache.org/nutch/HttpAuthenticationSchemes
+
+ HTTP-POST Authentication Support
+ Http Form-based Authentication is a very common used authentication 
+ mechanism to protect web resources. We extend the 'auth-configuration' 
+ to include information about http form authentication properties as shown
+ in the following example:
+
+ Example:-
+   <credentials authMethod="formAuth"
+                loginUrl="http://localhost:44444/Account/Login.aspx"
+                loginFormId="ctl01"
+                loginRedirect="true">
+     <loginPostData>
+       <field name="ctl00$MainContent$LoginUser$UserName"
+              value="admin"/>
+       <field name="ctl00$MainContent$LoginUser$Password"
+              value="admin123"/>
+     </loginPostData>
+     <additionalPostHeaders>
+       <field name="User-Agent"
+              value="Mozilla/5.0 ... Firefox/35.0" />
+     </additionalPostHeaders>
+     <removedFormFields>
+       <field name="ctl00$MainContent$LoginUser$RememberMe"/>
+     </removedFormFields>
+     <loginCookie>
+       <policy>BROWSER_COMPATIBILITY</policy>
+     </loginCookie>
+   </credentials>
+ 
+ it is critical that the following fields are substituted:
+  * loginUrl - the URL containing the actual <form>
+  * loginFormId - the <form id="$formId" attribute value
+    (or the 'name' attribute if no form is referenced by 'id' attribute)
+  * loginRedirect - if http post login returns redirect code: 301 or 302,
+    and value is true, Http Client will automatically follow the redirect.
+  * <field name="ctl00$MainContent$LoginUser$UserName" value="admin"
+    - the <input name"name" and user defined username value used to represent
+    the field and username respectively
+  * <field name="ctl00$MainContent$LoginUser$Password" value="admin123"

+  <description>Enables us to capture the specific IP address 
+  (InetSocketAddress) of the host which we connect to via 
+  the given protocol. Currently supported is protocol-ftp and
+  http.
+  </description>
+</property>
+
+<!-- file properties -->
+
+<property>
+  <name>file.content.limit</name>
+  <value>65536</value>
+  <description>The length limit for downloaded content using the file://
+  protocol, in bytes. If this value is nonnegative (>=0), content longer
+  than it will be truncated; otherwise, no truncation at all. Do not
+  confuse this setting with the http.content.limit setting.
+  </description>
+</property>
+  
+<property>
+  <name>file.crawl.parent</name>
+  <value>true</value>
+  <description>The crawler is not restricted to the directories that you specified in the
+    Urls file but it is jumping into the parent directories as well. For your own crawlings you can
+    change this behavior (set to false) the way that only directories beneath the directories that you specify get
+    crawled.</description>
+</property>
+
+<property>
+  <name>file.crawl.redirect_noncanonical</name>
+  <value>true</value>
+  <description>
+    If true, protocol-file treats non-canonical file names as
+    redirects and does not canonicalize file names internally. A file
+    name containing symbolic links as path elements is then not
+    resolved and &quot;fetched&quot; but recorded as redirect with the
+    canonical name (all links on path are resolved) as redirect
+    target.
+  </description>
+</property>
+
+<property>
+  <name>file.content.ignored</name>
+  <value>true</value>
+  <description>If true, no file content will be saved during fetch.
+  And it is probably what we want to set most of time, since file:// URLs
+  are meant to be local and we can always use them directly at parsing
+  and indexing stages. Otherwise file contents will be saved.

+
+<!-- HTTP properties -->
+
+<property>
+  <name>http.agent.name</name>

+
+  NOTE: You should also check other related properties:
+
+    http.robots.agents
+    http.agent.description
+    http.agent.url
+    http.agent.email
+    http.agent.version
+
+  and set their values appropriately.
+
+  </description>
+</property>
+
+<property>
+  <name>http.robots.agents</name>
+  <value></value>
+  <description>Any other agents, apart from 'http.agent.name', that the robots
+  parser would look for in robots.txt. Multiple agents can be provided using 
+  comma as a delimiter. eg. mybot,foo-spider,bar-crawler
+  
+  The ordering of agents does NOT matter and the robots parser would make 
+  decision based on the agent which matches first to the robots rules.  
+  Also, there is NO need to add a wildcard (ie. "*") to this string as the 
+  robots parser would smartly take care of a no-match situation. 
+    
+  If no value is specified, by default HTTP agent (ie. 'http.agent.name') 
+  would be used for user agent matching by the robots parser.

+  </description>
+</property>
+
+<property>
+  <name>http.robots.403.allow</name>
+  <value>true</value>
+  <description>Some servers return HTTP status 403 (Forbidden) if
+  /robots.txt doesn't exist. This should probably mean that we are
+  allowed to crawl the site nonetheless. If this is set to false,
+  then such sites will be treated as forbidden.</description>

+  <value></value>
+  <description>A URL to advertise in the User-Agent header.  This will

+   should be a URL of a page explaining the purpose and behavior of this
+   crawler.
+  </description>
+</property>
+
+<property>
+  <name>http.agent.email</name>
+  <value></value>
+  <description>An email address to advertise in the HTTP 'From' request
+   header and User-Agent header. A good practice is to mangle this

+  It is highly recommended to set db.ignore.external.links to true to restrict the outlink follower to URL's within the same

+    This schema is not minimal, there are some useful field type definitions left,
+    and the set of fields and their flags (indexed/stored/term vectors) can be
+    further optimized depending on needs.  See
+    http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/conf/schema.xml?view=markup
