Intercept and analyze responses from Zend_Rest_Server - php

Question

I used Zend Framework 1.11 to make a REST web service in PHP using the Zend_Rest_server class but I wasn't able to intercept and analyze the responses from Zend_Rest_server instances before these are sent to the clients.
To make the REST web service I use this snippet of code:
$server = new Zend_Rest_Server();
$server->setClass('Ws_dummy', 'dummy');
$server->handle();
Is there a method to log responses because I need to analyze them and I wasn't able to find a way to solve this need.
Thank you in advance for any help you can provide.
P.S. For example in SOAP web services I can do this:
$server->setReturnResponse(true);
$response = $server->handle();
or
$server->handle();
$response = $server->getLastResponse();
and analyze the responses

You can log Requests like this:
$writer = new Zend_Log_Writer_Stream('/path/to/logfile');
$logger = new Zend_Log($writer);
$logger->info( Zend_Debug::dump( $_REQUEST, 'Request-Dump', false );
You should do that before the Rest_Server handles the Request.
If you got further Questions - just ask :-)
Edit (added some useful information):
It may be helpful to understand that Zend_Debug::dump() method wraps the PHP function var_dump(). If the output stream is detected as a web presentation, the output of var_dump() is escaped using htmlspecialchars() and wrapped with (X)HTML pre-tags.
Edit #2:
You can return the Response of Zend_Rest_Server with:
$server->returnResponse(true);
before $server->handle().
Edit #3:
Be aware:
If I've read everything right you need to send the Headers by urself if you are returning the Response.
You can get/+set the Headers with:
$headers = $server->getHeaders();
foreach( $headers as $header ) header( $header );
