I am working with a balancer in mod_proxy where our traffic is distributed among two Weblogic servers. Occasionally, one of the servers goes crazy and starts returning 401’s. I know that by configuring failonerror=401 that I can have the bad server marked down for some amount of time. Beyond that we don’t know much. For instance, can I affect the amount of time that said server is down? When Apache does retry on the downed server and receives another 401 because the situation has not been corrected, is it possible to retry the transaction on the known good server?
Here is an example of what I have setup currently.
<Proxy balancer://server_cluster_ssl>
BalancerMember https://server1:8002 route=srvr1
BalancerMember https://server2:8002 route=srvr2
</Proxy>
<Location /abc>
ProxyPass balancer://server_cluster_ssl/abc stickysession=BALANCEID failonstatus=401
ProxyPassReverse balancer://server_cluster_ssl/abc
</Location> |

You can enable the manager page to manage the instances
| Code: |
<Location "/balancer-manager">
SetHandler balancer-manager
Require host example.com

| Is there any ability to retry the failed requests on the other server? |
