I am using Iconic's IIRF URL Rewriting Engine on IIS and the "fancy" URLs are something like this:
http://some-website.com/some-function/418/some-keyword-rich-filename.html
This example URL corresponds to:
http://some-website.com/some-function.asp?SOME-ID=418
Now inside the some-function.asp file I need to know the page that was requested by the browser. I went through all IIS variables but wasn't able to find the value /some-function/418/some-keyword-rich-filename.html inside any of them.
As a side note, I need this information to send 301 redirect to browsers. E.g. if the browser requests:
http://some-website.com/some-function/418/index.html
I first need to send the browser to:
http://some-website.com/some-function/418/some-keyword-rich-filename.html
And this is why I need the original url for comparison.
