• Client requests document using GET
• Server returns requested document via HTTP
• Client presents document to user

The GET model does not cater for sending information from client to server.

Solution is HTTP POST method which identifies a page by a URL and add the information to be sent in the HTTP message

HTTP POST may not return a document but use URL to identify the destination of the information

XHTML suggests GET should be used for idempotent requests (has no lasting observable effect on the state of the world)
