Re: Apache as Load Balancer question

Hi;
   You will also need to bump your version to 2.2.25 as failontimeout was not backported until then.

Try with failontimeout option set to on, by default it is "Off"

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?
