[PHP] Re: Load Balancing and PHP Sessions
A better way to set this up might be to use a reverse proxy in front of www1.test.com and www2.test.com. Users would go to www.test.com and the reverse proxy would forward communications between the front-end and the servers in the back, thereby balancing the load. Cookies should still work fine, regardless of the server that actually sets them. (I'm not sure if PHP's built-in sessions would work...) Since I'm assuming you're using Apache here, you'd most likely want to look into using Squid, which is a kick-ass proxy. Setting up the re-director is a bit of a hastle, since you basically have to write one from scratch, but it isn't too difficult. (There are lots of pre-made ones that can handle things like round-robins, randomness, all that jazz.)

Or save it to a common database... and it could have something to do with session.cooke_domain. A cooke set explicity to www1.test.com won't be viewable on www2.test.com, but if you set the domain to .test.com it will...
