Under CGI, each page hit has to fire up php.exe, run it, and exit. Next page hit, fire up php.exe, run it, and exit. That sounds horrendous. However, if your OS has a decent caching system, and you have enough RAM to hold all the processes you expect to be running, plus php.exe (rather small RAM footprint), it will stay in the RAM cache and not be nearly as slow as you might expect. Of course, we are talking about an MS product here, which may or may not be doing a decent RAM cache of processes in the first place... Buy more RAM. That's always a good idea. :-) AFAIK, the session stuff should work fine under CGI... It's just cookies and munged URLs/POSTs to schlep the ID around if they have cookies off... The Module versus CGI only matters for functionality (not performance, functionality) when there's some sort of inter-process communication involved between the server and PHP (or PHP and itself, I suppose could matter...) -- Richard Lynch | If this was worth $$$ to you, buy a CD US Customer Support Director | from one of the artists listed here: Zend Technologies USA | http://www.L-I-E.com/artists.htm http://www.zend.com | (this has nothing to do with Zend, duh!)
