Facebook and a stateless server

Question

I am making a Facebook application, I want to have a stateless server.The Facebook connect requests are from the server side. So when Facebook gives me a session which has to be maintained at the server this way my server won't be stateless.

When I'll load balance I can't have a simple load balancer instead it would need to know which users are on which server, something I don't want.

Any Ideas?

Answer 1

Assuming you can pass a token between web pages, one option is to store the state in a database using that token. That'll keep things independent of the webserver itself.

Answer 2

You can go with any of the following approaches depending upon your application usage:

1. Use sticky sessions.
2. Store session information in in-memory clustered cache. (e.g. solutions using Memcached)
3. Persist session related information in Database.
