I need your suggestion on hiding port number on redirected URL from browser... I have created a apache-tomcat bridge using following steps:

1) Deploying another application in separate context than ROOT under tomcat.
2) My default virtual hosts of apache listening on a dedicated port..say 80.
3) I wasn't allowed to use ProxyPass/ReverseProxy for some security constraint. So I have created another virtual-host listening on separate port with my own document root.(may be tomcat's deployment path for my app)... & used mod_jk to redirect the request to tomcat.
4) I have used RewriteRule to redirect the request generally for 80 port to my own virtual-host. with using [L,R] flags.

Now the redirected URL with the port number is getting visible in browser as it is explicit redirect... How can I hide/encrypt this port number to get displayed in browser?.... Don't ask to use [P] flag...it is nothing but the same of proxypass/reverseproxy....

So your URL looks like:

and you want to "hide" the 8090 bit?

Yes... My redirected URL is showing the port number. I want to hide this port number from URL in browser...

You aren't going to do that without proxypass/reverseproxy,.. or perhaps some iptables wizardry.
