Use of Apache proxy module to connect to Tomcat

Taking a look at Orion I just bumped on this one:
  http://www.orionsupport.com/articles/apachefrontend.html

Their solution to use Apache as a front end is:
  "Use Apache as a reverse proxy."

And there is even a sample for httpd.conf:

  ...
  LoadModule etc..
  LoadModule proxy_module /path/to/apache/library/libproxy.so
  LoadModule etc..
  ...

  <VirtualHost www.bigcorp.com>
      ProxyVia On
      ProxyPass /myapp http://orion.private.bigcorp.com:9876/
      ProxyPassReverse /myapp http://orion.private.bigcorp.com:9876/
      ...
  </VirtualHost>


Is this possible for Tomcat too? Pros and cons?


Thanks and have fun,

Thanks Jon,


That gave me a good enough perspective of the pros and cons. I have a 
scenario where using the proxy could actually be better.


Have fun,

Of course it is.

Proxy HTTP is probably not as efficient as a lightweight protocol (ie: AJP),
especially if the two systems are running on the same box (ie: local
sockets).

It also doesn't solve the configuration issues.

All you are doing in this case is putting another layer in front of the
Tomcat HTTPd. I don't see a reason to do that when the Tomcat HTTPd works
just fine. All you are gaining is the Apache module features (like
mod_rewrite).
