in reply to How can I create a file named "default.asp?11=1"?

Is '11=1' not part of your Get? Normally pages are created as 'pagename.(asp,pl, cgi, etc)'. The question mark tells the page that there are parameters coming in. For this one, 11 is 1. So if you create an asp page as default.asp then call it passing ?11=1.
If it's vbscript (ASP) then you can just put in tags...
<%=response.write 11%>
and it should print out 1.
