Hi all!  
I want to proxy\_pass depending on the value of the accept header. I have  
lots of locations and I wanted to add in a single place a validation  
that  
if accept header is 'text/html" it should proxy\_pass to some specific  
upstream. Else, just go ahead and try to match a location.

Is that possible?

Thanks!

Jonathan

Perhaps something like:

# http level

map $http\_accept $my\_upstream {  
default misc\_upstream;  
~text/html html\_upstream;

}

upstream misc\_upstream {  
server 127.0.0.1:8080;  
}

upstream html\_upstream {  
server 127.0.0.1:8088;  
}

# server level

location / {  
#… your stuff  
proxy\_pass http://$my\_upstream;  
}
