Thanks Erwin,

But it's not how the display in online.php looks to visitors I'm worried about - my concern is that if online.php is showing the session hash for the robot visitors, the robots must be getting the session hash somehow and thus they will not index my forums well.

I thought the whole point of the rewrite rules was to get rid of the session hash because some search engines refuse to list pages with a session hash, but it looks like despite following the rewrite rule URL's, a unique session hash is still being somehow served to the robots? (and to me as a "test robot" by simply opening a different browser as an un-logged-in visitor visiting one of the mod-rewrite URL's in the first post which isn't supposed to generate a session hash I thought... but a session hash still shows up in online.php for the guest visit I just created)
