thin

I have a multiple instances of thin running behind apache 2.2's mod_proxy. The problem I have is that a couple pages, by design, take a while to run.

If I just configure apache the obvious way (just add the thin urls as BalanceMember lines and no other configurations) then what happens is if someone clicks on the long-running page, then if enough web requests happen while it is running, someone eventually gets the same thin server and has to wait.

Does anyone have some best practices or suggested configuration for mod_proxy and thin?

Ciao!

as seen on Stack Overflow - Search for 'Stack Overflow'
I am wondering conceptually how load-balancing works on the EJB-level (not web session replication) with Java EE containers like Glassfish. From what I have gleaned your remote interface is a proxy that delegates your call to one of many servers you may have in an environment. If things fail are… >>> More
