mod_proxy_ajp

["Fenlason, Josh" <jf...@ptc.com>]

With the new proxy_ajp module it doesn't seem possible to only pass
dynamic content to the servlet engine as was possible with mod_jk.  
 
With mod_jk you could have apache serve static content and tomcat serve
dynamic content:
JkMount /servlet/* ajp13
JkMount /*.jsp ajp13
JkMount /*.jsp/* ajp13
 
As far as I can tell, there aren't any proxy directives to accomplish
the same thing.  Am I missing something?  Or is this by design?  If so,
is there a recommended way to accomplish the same thing using proxy_ajp
and other modules?

By the way, I couldn't find anything about the ajp:// protocol in the 
mod_proxy or mod_proxy_ajp documentation page, I got it from a mod_proxy 
presentation on http://people.apache.org/~mturk. So I'm not 100% sure it works 
this way. If it does, could someone add it to the documentation?

I think the following should work:

RewriteCond %{HTTP_REQUEST} *.jsp
RewriteRule ^/(.*) ajp://tomcat.host/$1 [P]

That's specific to mod_jk.  AFAIK, it won't do anything at all for 
mod_proxy_ajp.

I discovered another method today: I had to install a tomcat connector today, 
and found the following in the documentation 
(http://tomcat.apache.org/connectors-doc/howto/apache.html):

Starting with mod_jk 1.2.6, and under Apache 2.0, it's possible to exclude 
some URL/URI from jk processing by setting the env var no-jk, for example with 
the SetEnvIf Directive.

So something like

SetEnvIf Request_URI !.*\.jsp no-jk=true

should do the trick.
