Remove PHPSESSID from URL

Not only do URLs with PHPSESSIDs look terrible, but they could easily be thought of as duplicate content. You've probably seen them:

Something like this perhaps...

...index.php?PHPSESSID=6834tgksdfdadgfdgaglkghd

Yuck. You can easily turn that off with a line in your .htaccess file:

php_flag session.use_trans_sid off

And that should do it!
