POST

Pages generated by an HTTP POST operation are always cached. The Web browser uses POST operations whenever an HTML FORM statement specifies METHOD="POST" .

GET

Pages generated by GET operations are never cached because the Internet Transaction Server (ITS) explicitly sets a no-cache option in the HTTP header when the page is sent to the Web browser. It does not matter what caching options are set in the Web browser. The Web browser uses GET operations for hypertext links and FRAMESET documents.

If you have a hunt around with Google you'll be able to find more info on web service calls including non-ABAP specific examples that should help you understand the nature of the logic you are looking at ... for example the following page explains what the ASMX (ASP.Net) extention URI file will be doing in support of the post / get.
