Well, I use PHP sessions.  If the user has Cookies totally switched off,
then sessions will not work unless you pass the special SID variable around
appended to all your internal links.
e.g. <a href="http://www.mydomain.com/1?<?php echo(SID)?>">

which after PHP parsing comes out something like:
<a href="http://www.mydomain.com/1?"> .... if cookies are enabled
<a href="http://www.mydomain.com/1?PHPSESSID=abcdefgh123456789"> .... if
cookies are not enabled.
</end>

While I can't answer you question about mod_rewrite as I've never played
with it, the following snippet will test the cookie (ShoppingCart) and
append the session only if it's needed. Therefore no extra "?" in the URI.
Obviously watch for wrap...
print ("<a href=\"../onlinesales/shop.php".(!$ShoppingCart?
"?session=$session":"")."\">Shop</a><br>\n");

Obviously, when there's other fields I append it to the end of the URL with
an ampersand.
<a href=\"shop.php?category_id=$category_id".(!$ShoppingCart?
"&session=$session":"")."\">$category</a>
