That would be great... I've searched around and can find various places talking about doing it but nothing that really paves the way.

It doesn't do "nothing" its gets stored in the MD5 doesn't it?
Here it is...
Add in you htaccess

Thanks. I tried it and it gave me a 500 error.

What I originally was thinking, it seems like if you knew where $session[sessionurl] is given a value you could just cancel it out. It makes sense to me but I can't find where it's handled.

Its in the templates :) Navbar everywhere. Umm just search for that in templates you'll find it. Recommended its safe to have them on, when users cookies are off the sessions show up in the URL.

I mean find where the session variable is actually given the session id, somewhere in the php files or wherever (I've looked but cant find where). Removing the session variable in the templates is an option, but I wanted to keep the functionality for members and/or only in my forum, plus that would be a PITA to remove them all from the templates.

I guess Session URL is helpful, you dont need to "remove" it.

Thanks for trying to help.

I actually just came up with exactly the solution I was looking for.

A simple plugin using global_start

It works!

That turns it off?

Yup, it removes the session id from all links. I also added a conditional so that it only happens for guests. This way when a member logs in and isn't allowing cookies, everything works completely like normal.

Im sure you read my post explaining what it does right? You shouldn't remove it. Oh well your choice, good luck!
