Need help with special relay setup.

[DBR]

Okay, here is the deal.
My small station that I run from home is running out of space so I need to add a relay. All this can be fixed so this is not my issue.
Redirecting the listening links on my page to the relay is a simple task. But my experience says that this is not a good solution. Been there, done that.
So this is what I want to do:

I want to reduce the max listener limit on the main server to only the relay (1 listener). But instead of putting new links on the homepage to the relay I want (This is important!) the ordinary listening link (main server) automatically redirect the listener to the relay server without the listener to know. The less they know the easier it is for them. This is a fact I have learned.

On my page I have a link that’s point to a *.pls file I have on the server. This file then links the listener to the stream.
Is it in this file I should with notepad, add the relay server?
If so, how should the edited text file looks like when this is done?

Ex.
[Playlist]
File1=http://myserver:8000

All this In short:
I want the main server automatically redirect the listener to the relay server without the listeners need to learn new links etc.
I want the main server to be shown on shoutcast, not the relay. So when a listener clicks on the listen link the listener connects to the main server and the main server redirect the listener to the relay.
Hope I have made myself clear what it is I need help with.

Now I need your help how to do this.
Best regards!
