I currently have a huge problem. Two days ago my site running on one server was too much, so I purchased two more and had them clustered (rsync and load balanced).
I then start noticing that a user would hit server-1 and then on the next request hit server3 but that their session was still on server1 instead of server3 and they were no longer logged in.
I was recommended to use memcache for session stores.
My script already uses $_SESSION.
Can we get memcache installed and enable session handler support and set
session.save_handler = "memcache"to force php to use memcache?Is there any application programming that needs to be done to use memcache?
Will this solve my session between server issue?
Are the session stores stored on all the servers when they are created or is one like a master memcache server?
I'm using the codeiginiter framework
