SessionID in URL... How to avoid ?

Sometimes when i search google, i see a site of mine show up with a link with SID= ... in it ?

How can this be avoided? When i go to the site in question i dont even see the SID in the url ...

 

What script are you using on the site? The person who made it should be able to help.

 

What script ?
All code is custom made in php by myself.

 

The SID is not showing in my browser when i start a new session.

 

You could try this:

At the top of the php file:

ini_set('session.use_trans_sid',false);

PHP:

if that doesn't work, try adding in .htaccess:

php_flag session.use_trans_sid off 

Code (markup):

 

Thanx man, i put the line in my htaccess file.
That was the code i was looking for... It's more SEO-friendly.
