Hello everyone, I have a web server that is load balancing two tomcat servers
using the proxy module, all is working well but now I need to add a third one,
but we need to send very specific user_agents to that third server. The URLs
must be the same.
Right now my configuration looks like this:
ProxyRequests Off
ProxyVia Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
<Proxy balancer://cluster>
BalancerMember ajp://server1:8009 route=as1 loadfactor=50
BalancerMember ajp://server2:8009 route=as2 loadfactor=50
</Proxy>
ProxyPass / balancer://cluster/ stickysession=JSESSIONID
ProxyPassReverse / balancer://cluster/
I've bee looking to the mod_rewirte module, but I'm not sure how I could add
the third server and only send the specific user agents to that server.
This can be done fairly easily using a rewritecond:
RewriteCond %{HTTP_USER_AGENT} /some/matching/regex/
RewriteRule / ajp://server3:8009/ [P]
HOWEVER, this cannot be done inside the context of your balancer -
unless you do all three this way.
So you lose the sessionID.
