HTTP Server

Within DTF it is possible to start your own HTTP server that will respond to any type of HTTP method and be able to construct an HTTP response to your required needs. You'll find that you have to be a bit careful when starting and shutting down the httpserver because otherwise you may create a test that gets stuck waiting for a parallel executed http_server that doesn't end because you haven't issued the shutdown correctly. A simple recipe to follow when using the http_server tag can be seen in the following lines:

<parallel>
   <http_server port="28080">
      <http_listener method="PUT" path="/testpath" />
   </http_server>
   <try>
      <log>Do something...</log>
      <finally>
         <http_server command="stop" port="28080" />
      </finally>
   </try>
</parallel>

The previous template works well because after staring the HTTP server we're very careful to protect the stop command within a try/finally statement that guarantees we'll always stop the server before proceeding from whatever client activity we have tried to execute.
