WAP Model
The user opens the mini-browser in a mobile device. He selects a website that he wants to view. The mobile device sends the URL encoded request via network to a WAP gateway using WAP protocol.
The WAP gateway translates this WAP request into a conventional HTTP URL request and sends it over the internet. The request reaches to a specified web server and it processes the request just as it would have processed any other request and sends the response back to the mobile device through WAP gateway in WML file which can be seen in the micro-browser.
Wireless Application Protocol
The Wireless Application Protocol (WAP) is a set of communication protocols and an application programming model based on the World Wide Web (WWW). Its hierarchical structure is quite similar to the TCP/IP protocol stack design.
