sticky sessions :: Load Balancing :: RE: session tracking across a server farm

Kelvin, The trick you need is called 'sticky sessions'. Which are you using to balance the load on your server farm? . Cisco LocalDirector . Dell BigIP . An RFC2391-complaint LSNAT router . Linux 2.4 iptables . Redundant DNS entries (not effective) . Microsoft Windows 2000 Advanced Server's LB NAT util The Cisco LocalDirector ($$$) can do sticky sessions, i.e. keep a session going to one box behind it, by matching a cookie or a substring on the URL. Hey, HONK if anyone is doing sticky sessions with php4... pls! :) montyd > -----Original Message----- > From: Kelvin Luck [mailto:kelvin@sasdesign.co.uk] > Sent: Monday, April 30, 2001 11:14 AM > To: php-windows@lists.php.net > Subject: [PHP-WIN] session tracking across a server farm > > > Hi, > I am just writing a user authentication system in php.
