refrencing the current URL

I have been looking for this for a week+ and have gotted nothing 
but the proverbial 'blank stare', so perhapse it does not exist.

What I need to do is refrence the current URL in a hotlink (as an 
argument in a CGI call).
It seems to me that a keyword reserved for this purpose would be a
natural thing in HTML.  The client would do the substitution before
making its request.
i.e.:

<A HREF="/some/cgi-bin/script.pl?$Current_URL>

Mosaic (my client) would actualy request 
<A HREF="/some/cgi-bin/script.pl?http://the/current/URL.html">

This doesn't seem hard to do on the client end and I think it 
would be very useful.  Does something like this exist in HTML or 
HTML+?  OR, is there anothere way to do it?
