Re: Download redirector for debian-cd available

Hi,

is it possible to define different priorities for different autonomous 
systems?

The result I want to be realized is that a mirror which is connected to 
several networks (e.g. on a internet exchange point like 
mirrors.n-ix.net) is preferred from the networks it is connected to when 
in that networks no own mirror exists.

Maybe there is another way to realize this.

The problem will be to hold this configuration up to date.

Greetings,
Christian
