WebFarms and Sessions

[eluser]BrianDHall[/eluser]
With this many different frontends I would assume you have a single database server they all access, right? Then unless you want to share a cookie across domains, as darkhouse and Wuushu refer to, you can just use regular CI sessions and configure it to use your MySQL database.

Otherwise getting sessions to work across multiple domains and servers sucks, because you have to use a query string or rely on some sort of AJAX solution.

It does matter, in a big way, whether or not you are using 8 front-end load-balanced sort of solution, or if you have 8 different sites on different domains on different servers.
