Unless it doesn’t. Which is where the hard part comes in. As a client there’s no way to see the raw HTTP response from the server. You can grab the Zend_Http_Client from the Zend_XmlRpc_Client. This will give you access to
which is how Zend_XmlRpc_Client sends the request. The response however, is much harder to get. When Zend_XmlRpc_Client receives a response it uses a Zend_Http_Response, but it’s never stored.

To get around this I added a variable to the Zend_XmlRpc_Client to store the Zend_Http_Response before it’s destroyed. Then added in a function to return it and voila. To check the raw response you just have to
