I’m running Oracle Collab Suite on port 7777 and 7778. Oracle installed  
its own Apache and hacking it has proven to be difficult. For one thing,  
I can’t seem to get VirtualHost to work correctly. Since it doesnt use  
port 80 by default, I decided to put nginx in front of it. I managed to  
proxy pass port 80 to 7778. However, it doesnt stop there. Here’s how  
things are now.

My mail is pointed to the following URL:  
[http://mail.domain.com:7778/ocsclient/](http://mail.domain.com:7778/ocsclient/)  
My conferencing portal is pointed to:  
[http://mail.domain.com:7778/imtapp/app/prelogin.uix](http://mail.domain.com:7778/imtapp/app/prelogin.uix)

As you can see, the URLs are pointed to mail because that’s what the  
machine name is called. I managed to create a CNAME which works but once  
it redirects after you log in, it goes back to  
[http://mail.domain.com:7778/](http://mail.domain.com:7778/)…  
So, two things …

1 - How can I hide the port number, I think I got it to work using  
proxy\_pass but that only seems to work for one “server.”

server {  
listen 80;  
server\_name [mail.domain.com](http://mail.domain.com);

```
location / {
  index index.html;
  proxy_pass http://mail.domain.com:7778;
}

```

}

I added a second “server” directive for “[conference.domain.com](http://conference.domain.com)” but it  
sends me in a loop.

2 - How can I rewrite my URL so that if I go to “[conference.domain.com](http://conference.domain.com)”  
it doesn’t change to “[mail.domain.com](http://mail.domain.com).” Don’t forget the app was  
installed and takes the hostname of the server which is [mail.domain.com](http://mail.domain.com).

However, it rewrites "Location"s header only. It can not rewrite links  
inside HTML.
