Hello, Is that possible to map Port to URI with Rack?

I want to integrate Site writen in Ruby with Zimbra Mail and some other  
systems:

Site URI: [www.company.com/site](http://www.company.com/site) \<= localhost:80  
Zimbra Mail: [www.company.com/site/mail](http://www.company.com/site/mail) \<= localhost:81  
App XXX: [www.company.com/site/xxx](http://www.company.com/site/xxx) \<= localhost:XX

As i understand it’s possible to do with Unix Port Forwarding and Some  
Apache Machinery, but it would be a lot simpler and better to do it with  
Rack.

Thanks!

You want a proxy.

Nope.

Apache, or nginx, or perlbal, or…

You may find a proxy that someone has built on Rack, but you really  
don’t want  
to do this yourself. I’d recommend you just use nginx.
