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.
