Hello, I have a couple apache http servers (v2.2) proxying requests to a handful of tomcat servers (6.x) serving applications in individual contexts. I have a ProxyPass line for each context in my config. I'm utilizing the proxy balancer and its working well; if I kill "tomcat1", apache will quit sending requests to it as expected. However, if I stop a context (to simulate a crashed app) and leave tomcat running, apache seems to consider the balancer member alive. Obviously, this results in "unavailable" responses from Tomcat to the end user. I realize there are multiple technologies at work here (apache balancer, AJP, and tomcat). Is it possible to configure apache to check each context listed with a ProxyPass directive for availability, and execute logic based on that (e.g. remove the balancer_member, or select another balancer_member for requests to that ProxyPass item)? Based on my reading of the documentation and archives, it appears the balancer is concerned with connectivity to the http/ajp connector of the back-end server, which makes sense. I understand HTTP isn't designed to do what I'm asking, but I'm hoping there is some special functionality in AJP that could allow the aforementioned to be possible. Thanks for any input. --- httpd Configuration Snippet --- <Proxy balancer://some-balancer> BalancerMember ajp://tntest-app-a-1:8009 loadfactor=1 route=tomcat1 BalancerMember ajp://tntest-app-a-2:8009 loadfactor=1 route=tomcat2 ProxySet lbmethod=byrequests stickysession=JSESSIONID|jsessionid scolonpathdelim=On </Proxy> ProxyPass /testApp balancer://some-balancer/testApp ProxyPass /anotherApp balancer://some-balancer/anotherApp --- System Info --- OS: Ubuntu 10.04 LTS Apache httpd: 2.2.14 (Ubuntu) Tomcat: 6.0.24 AJP Protocol version 1.3 Kyle Harper This communication and any attachments are confidential, protected by Communications Privacy Act 18 USCS § 2510, solely for the use of the intended recipient, and may contain legally privileged material.
