[TYPO3-dev] session handling

[Martin Kutschker]

Hi!

I noticed that on each hit TYPO3 queries the session tables 4 times. Two 
times for the FE and two times for the BE.

One hit is quite clear to me, the other is in comments stated to be 
necessary for auto-login. But why do I need another lookup in the 
session table, and do I really need an auto-BE-login in the FE?!? Does 
this really work? I think a heavy-load site will not need a 
BE-auto-login (and maybe FE editing) and will only be too happy to get 
rid of two additional (and possibly pointless) DB queries.

Can somebody who know the authentication code well enlighten me?
