I'm aiming to be closer to 100/sec than 1/sec. If I code for 100/sec it should handle anything under that like a breeze. 100/sec is a lot of hits though. > ".htaccess" can be made to pull data from a database, so I don't think > there's a clear distinction to be made there.

I've done this sort of authentication before, but have heard conflicting reports about what is more *secure*.

The hardware is not really the issue here although, to begin with everything will be stored on a single machine (dedicated AMD K6 3D with 256MB RAM). This can be upgraded as required. I'm interested in what is considered to be the best authentication scheme (in terms of speed and security) for a server taking a lot of hits (let's say 100 minute) and having a large number (10,000+) of registered users? Keep the feedback coming, I would like to see some level of consensus on a scheme ;-) Cheers, Brad -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
