In computing, POST is a request method supported by HTTP used by the World Wide Web. By design, the POST request method requests that a web server accepts the data enclosed in the body of the request message, most likely for storing it.

The CGI script passes its output, usually in the form of HTML, to the Web server, and the server relays it back to the browser as its response to the browser's request. [2] Developed in the early 1990s, CGI was the earliest common method available that allowed a web page to be interactive.
The second model referred to by the document ("model 2" in the ordering) was an improved method that combined servlet technology with JSP technology. The specific difference listed was that a servlet would intercept the request, place the content to render into a request attribute (typically represented by a JavaBean), then call a JSP to render ...
