It is basically like sending another GET request back to Apache. It goes through all the same layers and the php or cgi script that is run sees it as a completely separate request. It has no idea it is part of a single .shtml page. So no, there can't be any sharing of resources across multiple include virtuals from a .shtml page. I would suggest doing the bulk in PHP and if you need a Perl cgi run, use PHP's virtual() function which does the same as include virtual in a .shtml page. -Rasmus
