Hello,

i tried to build content adaption with nginx. For example requesting  
[http://example.com.reverseproxy.com](http://example.com.reverseproxy.com) will serve you content from  
[example.com](http://example.com) with substituted url from [http://example.com](http://example.com) to  
[http://example.com.reverseproxy.com](http://example.com.reverseproxy.com)  
It works great but now i have to substitute Location Header on http  
status code 301. Anybody knows how this is possible? I tried  
subs\_filter. It works great on body subsitution, but not on headers.

Sorry for my bad english.

Greetings  
Anthony
