Hi All,

I would like to know if I can configure nginx to utilise different set  
of  
cache zone conditionally.

For example

- if the user-agent is a mobile device then use proxy\_cache zone called  
“mobile\_proxy\_zone”
- if $http\_cookie contains the word “semi-static” then use proxy\_cache  
zone  
called “semistatic\_proxy\_zone”
- if user IP address is 8.8.0.0/16 then use proxy\_cache zone called  
“gws\_internal\_zone”
- Serve the rest using proxy\_cache zone default\_zone

At this point, I don’t mind having the rules as first hit first serve (  
ie  
if it matched user-agent then just use mobile\_proxy\_zone even when the  
semi-static is present on the $http\_cookie )

Is this do able ?  
Can we specify the proxy zone dynamically ?

Regards,  
Rianto Wahyudi
