grabbing the url of a url rewrite 1

[tyutghf]

My website runs behind a series of rewrites so

/article.asp?article=hello-bob becomes

/article/hello-bob/

I have a form on each page, submitting the form takes them away temporarily with the aim of bringing them back after everything is complete. On the form I have a hidden field grabbing the url of the page they were on before submitting the form.

This works perfectly on pages that aren`t url rewritten. On an url rewrite page (i.e. the example above) server variables (URL, SCRIPT_NAME etc) all bring back the page they are on as

<input type='hidden' name='wherefrom' value='/article.asp' />

is there a way to make server variables to grab the url rewriten url instead?
I tried to use the REFERER server variable on the form page but that has the same issue (and others of not always showing the referer sporadically).

Thanks

concatenate server variables SCRIPT_NAME and QUERY_STRING?

QUERY_STRING: "Returns the query information stored in the string following the question mark (?) in the HTTP request
