//hack-1 : support delete method for html
//Currently, browsers do not support delete method. For html media,
//delete operations can be supported through POST. Redirect html
//client POST request for delete operation to DELETE method.

//In case of delete command reosurce, we will also create post method
//which simply forwards the request to delete method. Only in case of
//html client delete request is routed through post. For other clients
//delete request is directly handled by delete method.
