I was browsing the web and when I came across a website that I thought it might be quite intresting to see what server side technology they were using.

The only thing I could find was that on a form on a web page it pointed to a "SVC" file e.g.
<form name="loginform" method="post" action="form\SVC" id="loginform">
I have never seen anything like this before, does any one have any clue what it can be?
