PHP session.auto_start "on" on server

How can I work around it?

[Longhaired Genius]

I chose minibb for my forum because it doesn't use PHP session IDs that might interfere with Google indexing. But my host has session.auto_start set to "on" (heaven knows why) and now my forums have unwieldy urls like:
href="index.php?action=vtopic&forum=1&PHPSESSID=eaee77a062cebc017a708b9212c81772"

Is there anything I can do to avoid this in my PHP code or even with the mighty .htaccess. I wasn't thinking of rewriting the urls, but somehow turning off the session.auto_start for my pages.

Any help would be very welcome.

Put this..

<IfModule mod_php4.c>
php_value session.auto_start 0
</IfModule>

in your .htaccess file.

Yeah! Thanks, grahamstewart.
