yes, trans-sid will never rewrite an absolute path.
So just go through your entire site and rewrite all your links as so...
"http://www/mysite.com/path/to/file.php"
...
Bwahahahahahahah!!!
Happy not-quite April fools!
just enter this somewhere at the top of your pages:
ini_set("session.use_trans_sid", 0);
that disables the use of trans-sid for that one script.
...man, I bet I had you sweatin' there 🙂
