parsing url in ASP

[boccio]

I see quite a number of asp (and somewhat other scripting languages) pages that parse url in a way I'm not familiar with.... I used to seeing pages that parse url in standard way, like:
somepage.asp?a=value1&b=value2, etc.... but what about this?

I have hard time believing that there is actually a page like this, called 0,1,2,3,4.asp..... so, can anyone familiar with this shed some light on subject?

thx in advance
