∟Receiving Returning Values as a HTTP Response

This section describes how to receive the returning value XML message from the remote machine.

The last item of the XML-RPC specification is about how to returning values of remote method call can be received as a HTTP response.

XML-RPC defines that the returning values must be delivered as a HTTP response back to the local host with the following rules:

Header line, "Content-Type", is required and must have "text/xml" as the value.
Header line, "Content-length", is required and must give accurate value.
The response body must be an XML file with a single "methodResponse" element.

Here is an example of an XML-RPC response:

HTTP/1.1 200 OK
Connection: close
Content-Length: 200
Content-Type: text/xml

<?xml version="1.0"?>
<methodResponse>
 <params>
  ......
 </params>
</methodResponse>
