∟Sending a Remote Method Call as a HTTP Request

This section describes how a remote method call XML message can be delivered to the remote machine as a HTTP request. Extra request head lines are used.

The second item of the XML-RPC specification is about how to send a remote method call as a HTTP request.

XML-RPC defines that a method call must be delivered to the remote host as a HTTP request with the following rules:

The request must use the POST method.
Header lines, "User-Agent" and "Host", are is required.
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 request body must be an XML file with a single "methodCall" element.

Here is an example of an XML-RPC request:

POST /pathName/progName HTTP/1.0
User-Agent: MyAgent/1.0.0 (Linux)
Host: kermit.dot.com
Content-Type: text/xml
Content-length: 300

<methodCall>
 <methodName>somePackage.someSort</methodName>
 <params>
  ......
 </params>
</methodCall>
