/**
 * An HTTP request using the DELETE method. 
 * RFC 2616 http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html defines: 
 * 
 * 9.7 DELETE
 * 
 * The DELETE method requests that the origin server delete the resource identified
 * by the Request-URI. This method MAY be overridden by human intervention (or other
 * means) on the origin server. The client cannot be guaranteed that the operation
 * has been carried out, even if the status code returned from the origin server
 * indicates that the action has been completed successfully. However, the server
 * SHOULD NOT indicate success unless, at the time the response is given, it
 * intends to delete the resource or move it to an inaccessible location.
 * 
 * A successful response SHOULD be 200 (OK) if the response includes an entity
 * describing the status, 202 (Accepted) if the action has not yet been enacted, or
 * 204 (No Content) if the action has been enacted but the response does not include
 * an entity.
 * 
 * If the request passes through a cache and the Request-URI identifies one or more
 * currently cached entities, those entries SHOULD be treated as stale. Responses to
 * this method are not cacheable.
