Re: Apache as Load Balancer question (Apache Users)

Hello,

I’m using Apache as a Load Balancer and have a question regarding the Balancer configuration on version 2.2.24 (Mac OS 10.8.5).

This is my scenario: When some of the members in the group are down, sometimes the LB does not take the request and the client gets a timeout; if I remove those members from the config and restart Apache, all the requests are served (my configuration for the LB is below).

Is my configuration missing something? maybe a retry or other timeout param?
