Transparent Tomcat to get to Apache

[Mark Walker]

After hearing someone describe this question, I'm posting this as a
matter of curiosity. The question, if I understand it clearly, is this:
With a Tomcat server in front of an Apache server, how can the Apache
server be accessed directly when the Tomcat server is the one facing the
outside? The reason for wanting to do this is to perform remote
administration of the Apache server without hard-configuring ports or
other workarounds that might impair the functionality of either server.

Possible solutions under consideration include configuring the Tomcat
server to ignore GET requests for php pages and to pass them on to the
Apache server.

Certainly configuration file code would be appreciated by all interested
in this topic.

Thanks for your thoughts,
Mark

This is done quite regulary. Not for the purpose you suggest but to use
Apache's cache for static content, and tomcat for dynamic content.

To see how to do it, try one of the manage pages discussing the subject.
Here's one at the source: http://tomcat.apache.org/connectors-doc/ .

I would recommend webmin for that instead.

It's a lot more advanced. You can setup URL patterns with regex
expressions that gets routed from the front to the backend server. It
can be conditional and a lot more "cool stuff".

See the above link. There's lots of examples, explanations and reasons
for doing it or not doing it.
