I feel like I read just about all the help that is out there when it comes to reverse proxying and HTTPD but it appears a lot is contradicting or not really working. Any help would be greatly appreciated.

We have a simple setup - Apache HTTPD in front of a few Tomcat servers.

The proxy should translate URL's like

http://domain.com/12345 -> http://internal:90/base/xhtml/user/55555555

My vhost is currently as follows:

Code:

 Servername domain.com
  ProxyRequests Off
 
  <Proxy balancer://b1>
    BalancerMember http://internal:90/ route=int1
  </Proxy>
 
  ProxyPreserveHost On
  RewriteEngine On
  RewriteRule ^/12345/(.*)   balancer://b1/base/xhtml/user/5555555/$1 [P]
  SetOutPutFilter proxy-html
  ProxyPass         /12345   balancer://b1/base/xhtml/user/5555555   stickysession=JSESSIONID|jsessionid nofailover=On
  ProxyPassReverse   /12345   balancer://b1/base/xhtml/user/5555555 


When I enter the external URL:
http://domain.com/12345 - I get redirected to http://domain.com/xhtml/user/55555555/login.xhtml

When I enter the external URL: http://domain.com/12345/login.xhmlt the form comes up but upon submit it redirects again to http://domain.com/xhtml/user/55555555/login.xhtml

Essentially I could get the site to work with the "long" URL but that is not desired as different scenarios will have to be satisfied down the road. I played with different variations but for some reason the destination app insists of going the /xhtml/user/..etc router.

Is there a way to force Apache to use the external URL? I tried getting it done with proxy_html_module but either I don't know what I am doing or it does not work either.

I wonder why you need the rewrite rule. Usually the ProxyPass and ProxyPassReverse should do it. I also wonder why you have a balancer with only one member ... maybe you just did not post the other members.

So without the rewrite rule

You have to enable mod proxy html

Code:
ProxyHTMLEnable On


Please consult http://httpd.apache.org/docs/current/mod/mod_proxy_html.html for the options.
