       <p>Apache DirectMemory has a server implementation (a servlet) to provide you a way to store your project remotely and to share those cached objects with various applications.</p>
       <p>Server side and client side (Java only) are provided.</p>
       <p>The exchange are based on http(s) exchange with the following implementations/format:
         <ul>
           <li>JSON format</li>
           <li>"binary" format: parameters are send via http headers</li>
           <li>text/plain format: you can send a text value(json object, xml etc..), the server will serialize the content and store it for you.</li>
         </ul>
       </p>
     </section>
     <section name="Exchange formats">
       <p>We simply use HTTP method names to resolve the action to proceed and depends on the Accept or Content-Type headers the format will be different :
         <ul>

           <li>DELETE to delete content ${webPath}/${key}</li>

         <p>Before using the client api, you must configure it using the following pattern:

             <param name="url" value="http://svn.apache.org/repos/asf/incubator/directmemory/trunk/server/directmemory-server/src/test/java/org/apache/directmemory/server/services/AbstractServletWithClientTest.java"/>

           Here you have a configured client. Have a look at DirectMemoryServerClientConfiguration javadoc for advanced options.

       </subsection>
       <subsection name="PUT Content">
         <p>
         With the Java client is something like:

             <param name="url" value="http://svn.apache.org/repos/asf/incubator/directmemory/trunk/server/directmemory-server/src/test/java/org/apache/directmemory/server/services/AbstractServletWithClientTest.java"/>

           You must check the method (response.isFound()) if true retrieve the object with: Wine wine = response.getResponse();
         </p>
       </subsection>
       <subsection name="DELETE Content">
         <p>With the Java api:
