 <h1 class="page">Providing Resources</h1>
 <div class="paragraph">
 <p>Extending the Apache Felix Web Console with new functionality is as easy as registering a <code>javax.servlet.Servlet</code> with at least the <code>felix.webconsole.label</code> service registration property set (see above).
 Providing resources is a bit more complex and requires more work on behalf of the plugin.</p>
 </div>
 <div class="paragraph">
 <p>Out of the box the Apache Felix Web Console plugin servces resources through the OSGi <code>HttpContext</code> used to register the web console with OSGi <code>HttpService</code>.
 This is done by registering resources with the <code>HttpService</code> below the <code>/res</code> alias.
 This mechanism though does not lend itself for easy extensibility.
 Therefore another mechanism has been chosen, which relies on similar mechanisms.</p>
 </div>
 <div class="paragraph">
 <p>A web console plugin may implement a <code>getResource</code> method which is looked up using reflection.
 This method is called by the <code>AbstractWebConsole.doGet</code> to check whether the request is actually for a resource.</p>
 </div>
 <div class="paragraph">
 <p>The method has the following signature:</p>
 </div>
 <div class="literalblock">
 <div class="content">
 <pre>modifier URL getResource(String path);</pre>
 </div>
 </div>
 <div class="paragraph">
 <p>Where the <em>modifier</em> may be <code>public</code>, <code>protected</code>, or <code>private</code> (if the method is declared in the class of the resource provider).
 It is suggested to use the <code>private</code> modifier if the method is declared in the resource provider class or the <code>protected</code> modifier if the method is declared in a base class of the resource provider.</p>
 </div>
 <div class="paragraph">
 <p>This method is called with the path info of the request (<code>HttpServletRequest.getPathInfo()</code>) and expects and URL to the resource to be sent to the client.
 If the path cannot be resolved to a resource the <code>getResource</code> method is expected to return <code>null</code> thus causing regular processing of rendering the page.</p>
 </div>
 <div class="paragraph">
 <p>If the <code>getResource</code> method returns an accessible non-<code>null</code> URL, the request is serviced by sending back the contents of the given URL.
 Simple caching support is included which handles the <code>If-Modified-Since</code> header and sets the <code>Last-Modified</code> header from the resource URL.</p>
