Mo,
"(we haven't found, in our initial research, a way to do this)"
You could format your variables before they're needed in the link
something like:
if(isset($x)) $x_link="&x=$x";
if(isset($y)) $y_link="&y=$y";
etc.
then your link would look like the following
<a href=someplace.com?slug=1$x_link$y_link....>someplace.com</a>
"slug=1" is used so that none of the preformatted variables need to start
with a ? instead of an &. if one, or several of the preformatted variables
are empty, the line just slides to the left and fills any vacancies. If all
your pages start with the same if(isset()) table, then the variables will be
passed around as long as the user stays at your site. No cookies or
sessions required.
Hope this helps,
Hugh
