Ok, I was reading up on the map module and it seems the right way to do  
this, howeaver I really couldnt think of a way to do this (without just  
using the if alternative way).

Blocking domains is what I want to do, my server blocks are per IP  
accepting everything for any domain, howeaver I want to filter certain  
[blocked] domains away by way of proxy passing or redirecting to another  
URL.

And I take it that the first block is the ‘default’ so I should add my  
‘bad-site’ block last like you have? Just clarification.

I really like the way you did this, way more clean than the if based  
system  
I was planning to use (and less evil).

You can use another server block for that domains.

It doesn’t metter if you add default\_server parameter to the right  
place.
