I have setup tomcat 6 on a server with several different instances which run on different ports

For Eg:


and so on...

These urls are available two the users using these and other applications Now I want to hide the ports on which each of the applications are running...

So that the user could see only something like this


What is needed to be done for this

I have achieved this for one url (i.e. one port) using the firewall rules and redirect the request on HTTP 80 port to the port that tomcat is listening..

But I want such patter to appear for all the urls...

How can I go about this?


HOST M/C : 64 bit

OS: Linux Redhat

Tomcat : 6.0

Install a real webserver, like Apache or nginx, and use it's built-in proxying capabilities (mod_proxy on Apache, and HttpProxy core module on nginx) to proxy the path to the appropriate Tomcat application running on a high port.

Thanks. But could you give me a little bit more details about it or say may be a link to a guide or something that can guide me to how to go about this process... – S.M.09 Mar 29 '12 at 9:42

Install apache and use mod_rewrite to proxy the requests to the backend tomcat applications.

Here's a sample snippet of apache config that should do it:

RewriteEngine on
#Optional - setup a log, useful for debugging
#RewriteLog logs/rewrite.log
#RewriteLogLevel 3

RewriteRule ^/myAPP1(.*) http://10.XXX.XXX.XXX:8080/myAPP1$1 [P,L]
RewriteRule ^/myAPP2(.*) http://10.XXX.XXX.XXX:8088/myAPP2$1 [P,L]
RewriteRule ^/myAPP3(.*) http://10.XXX.XXX.XXX:8082/myAPP3$1 [P,L]

Here's some helpful info regard mod_rewrite:

I tried using ReverseProxy and was successful in achieving the result. Could you tell me the difference in using Reverseproxy and RewriteRule. I would like to give Rewriterule a try especially if it makes a difference in the response time to the client. – S.M.09 Apr 1 '12 at 15:39
mod_rewrite is powerful and does more than proxying requests. Check out the documentation or some of the mod_rewrite guides available. It allows regular expression matching and URL manipulation. – Jason Floyd Apr 4 '12 at 7:02
