Cache only if no args?

I have a small question for you !
It is possible to cache the response from proxy_pass (that is filtered
by custom filters) _only_ if the request has no args? If the request has
arguments, it should be served from upstream and any temporary buffer
Request http://www.example.com/image.jpg <-- cache it
Request http://www.example.com/image.jpg?lowquality=true <-- don't cache
All assuming that the proxy_cache_key is just the uri without params
($scheme://$http_host$uri in the specific).
So, I should have only one copy of the file in cache and should be the
"clean" one. I don't want to cache any request that is processed by my
custom filters with different cache keys.
Thank you very much :)
