Hi,
I am trying to configure apache with mod_proxy and mod_rewrite to =
distribute load among "n" backend servers. I need to figure out a =
mechanism for detecting failures in backend servers so that requests can =
be directed to one of the working servers.

My requirements are as follows:
1. Load balance among "n" backend servers.
2. In case of server failure redirect the requests to the working =
servers automatically.
3. As and when the server comes up again, start sending requests to =
that server too.

Is there any way of configuring Apache to achieve this? I am using =
Apache1.3.26!

Warm Regards,
Paramdeep

I would take a look at mod_backhand or if you are using Linux at LVS
