We’re trying to proxy only certain assets like png|jpg|css only when the  
host header is a certain DNS name. I tried to do this in the proxy.conf  
file  
using something the example below but it doesnt like the if statement.  
Is  
there a way to have nginx do what I am looking for?

if ($http\_host = [dnsname.com](http://dnsname.com)) {  
location ~ ^/(stylesheets|images|javascripts|tools|flash|components)/  
{  
proxy\_pass [http://assethost](http://assethost)  
}  
}
