Fully qualified domain names

I've set up a RTC server and database in my local domain, and can log into the web UI with the following link:

https://mylocalhost:9443/jazz

If I send this link to another co-worker who happend to work in a different domain the above link does not work. That is because "mylocalhost" does not exist in his domain. To get around this issue, I can specify the full qualified name of the host instead....

https://mylocalhost.my.specific.domain:9443/jazz

This allows the user to see the login page and will validate his password. After the validation, it tries to go to the following link, but drops the fully qualified domain name...

https://mylocalhost:9443/jazz/web

I can get aournd this by adding the domain name back into the URL, but I want to know how to configure Jazz and RTC to always use the fully qualified domain instead.

Does anyone know how to do this?
