NAME

       Perlbal::Manual::FailOver - Fail Over mechanism in Perlbal

   VERSION
       Perlbal 1.78.

   DESCRIPTION
       How Perlbal's Fail Over mechanism works.

   Fail Over
       Whenever Perlbal fails to open a connection to a machine, it assumes that machine is not
       available and spreads the load between the remaining servers. It keeps trying to open
       connections to that server according to "error_retry_schedule".

       If there are no available servers, Perlbal will keep trying to open connections to the
       servers until "idle_timeout" is reached, upon which it will close the connection to the
       user. Clients interpret that closing differently: most will assume a 500 HTTP code, a few
       assume a 200 OK with empty content.

       For more information on parameters "idle_timeout" and "error_retry_schedule" see
       Perlbal::Manual::ReverseProxy.
