Re: [users@httpd] Location of rewrite rules when using mod_proxy in 2.2

[Chris Hane <chrishane@xxxxxxxxx>]

I will try to use the ProxyPass directive.  I think I tried that first 
and ran into a limitation that I want to do three things:
1) only redirect if the requests starts with /backoffice-production
2) if #1 then redirect to jboss on port 9009 if the url ends with *.its
3) otherwise redirect to tomcat on port 8009

Does ProxyPass accept wildcards?  I'll give it a try here shortly.

If there is a better way to accomplish what I am trying to do in those 
three requirements without using rewriting, I would appreciate a 
pointer.  I had searched the lists for similar criteria and thought 
Rewriting was the way to go.

The following are the all the entries I added to get this to work 
without any VirtualHost blocks.  Now I'm trying to get it to work with 
VirtualHosts.  Here are all the changes I made to the stock httpd.conf 
file (beyond standard things like ServerName and DocumentRoot).


<part of httpd.conf>

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

ProxyRequests Off

<Proxy *>
   Order deny,allow
   Allow from all
</Proxy>

RewriteEngine on
RewriteLogLevel 5
RewriteLog "rewrite.log"

######### JBoss
#example URL  some.domain.com/backoffice-production/some/path/edit.its
#example URL  other.domain.com/backoffice-production/other/path/edit.its

RewriteCond %{REQUEST_URI} /backoffice-production/(.*).its(.*)
RewriteRule ^/(.*) ajp://localhost:9009/$1 [P]

#example URL  some.domain.com/backoffice-production/js/functions.js
RewriteCond %{REQUEST_URI} /backoffice-production/js(.*)
RewriteRule ^/(.*) ajp://localhost:9009/$1 [P]


######### TOMCAT
#example URL  some.domain.com/backoffice-production/other/path2/edit.jsf

RewriteCond %{REQUEST_URI} /backoffice-production(.*)
RewriteRule ^/(.*) ajp://localhost:8009/$1 [P]

</part of httpd.conf>

Thanks,
Chris....
