Possible to blacklist all, whitelist some query parameters?

[lkraav]

Hey. If query parameters are able to cause some heavy work on the server, and we'd only like to allow a certain set of parameters through for caching, is this module able to perform full blacklisting?

It feels like I'd want

sorted_querystring_filter_parameter *;

with

sorted_querystring_filter_allow_parameter utm_*;

Your thoughts?

Or perhaps this module can do the sorting, and the rest can be achieved by http://stackoverflow.com/questions/26613147/remove-specific-query-parameters-from-url-in-nginx
