If I understand correctly, it sounds like you are doing: 
<form method="post" action="/cgi-bin/myScript?location=value">

[download]
and by doing so, you have no access to location parm via: 
my $location = param('location');

[download]
If this is the case, I would suggest you use a hidden parameter ala: 
<form method="post" action="/cgi-bin/myScript">
<input type="hidden" name="location" value="val">

[download]
you can then access the location value via the param call.

UPDATE: in re-reading, it appears that you are wanting the form var to appear in the browser location field for a POSTed form. If this is the case, then I am not sure there is a solution
