Of course it doesn't work, the setting is only inside the sublocation
created by if, and so after that, it's back on.

This is just my simplified and limited understanding of things...
Basically, if doesn't work the way people think it does in NginX. Some
more can be found at http://wiki.nginx.org/IfIsEvil .

A possible "workaround" might be to proxy to different back-end
nginx's based on the arguments, one with caching enabled, one with
caching disabled.
