Of course this can get tedious if the links in the content are hard to find (and also needs some CPU resources).

Re: Is there a GOOD AJP-based cluster reference?
At the risk of violating your request (not to point you to the documentation), I'm going to point you at the documentation. In particular: manual/mod/mod_proxy.html#proxypassreverse (from the Apache httpd docs) This will rewrite response URLs. However, there is a caveat. It will not rewrite any absolute URLs within the documents served. So if you have /context/somewhere/someplace inside a particular page, this link will be returned intact and the user will not be able to reach it. Again according to the document, you'll need to look at Nick Kew's mod_proxy_html (http://apache.webthing.com/mod_proxy_html/). There appears to be a tutorial on reverse proxying at that location as well. You may find it far easier to just rename the war file to ROOT.war and be done with it. . . . . just my two cents /mde/ - Original Message From: Jeffrey Janner jeffrey.jan...@polydyne.com To: Tomcat Users List users@tomcat.apache.org Sent: Thu, November 4, 2010 6:56:20 AM Subject: Is there a GOOD AJP-based cluster reference?

That's what I'm doing now Pid. Not sure if that's helping much since it seemed to work the other way round also. Switching the order still showed the same apparent behavior. See my response to Mark Eggers about how I've got it working right now. I'd love to get any more input from you if there is an issue on that configuration.

RE: Is there a GOOD AJP-based cluster reference?
In looking at the JSPs, the dev team is coding all the paths inside a c:url construct, which is why the context string is getting prepended to every path in the document. What was throwing me off a bit was the default doc was just a redirect as: -- %...@page contentType=text/html pageEncoding=UTF-8% % response.sendRedirect(login); % -- The browser would show this as http://hostname/context/login. My interpretation of the docs had me thinking that the context would get stripped as well, but it wasn't. Thus the confusion. I have managed to get it working with the following: Proxy balancer://mycluster BalancerMember ajp://prtltest01:8009/Portal route=tomcat1 loadfactor=50 BalancerMember ajp://prtltest02:8009/Portal route=tomcat2 loadfactor=50 /Proxy ProxyPass /Portal/static ! ProxyPass /Portal balancer://mycluster stickysession=JSESSIONID|jsessionid scolonpathdelim=On ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid scolonpathdelim=On Notice I don't have any ProxyPassReverse lines. From reading the docs, I'm not sure they are needed for AJP proxying. I'm trying to keep the Tomcat side of things fairly simple -- pretty much deploy the war direct from dev -- to keep there from being too many steps that could get screwed up when I'm not around and someone else needs to deploy. The process will be documented, but some people refuse to read directions correctly. Plus, the apache server will someday host multiple apps under one host, so having it work with the context as non-root now means less work later. Then again, I bf'ed and didn't put the static stuff in the proper tree structure under the htdocs dir. I just put them there as I got them. (There is no static directory on the Tomcat side, it's virtual. The dev team is doing weird stuff with this new product.) Let me know if you see any problems with the above config.
