You can indeed do it in pure VCL, but for long URLs it also means a lot more workspace consumption. If you want to increase you performance even further, vmod-querystring can sort too (if appropriate). The difference with std.querysort is that a vmod-querystring filter will both sanitize your URL and do the sorting with the same memory footprint: no extra cost (except CPU time obviously) comes from the sort operation. Another interesting feature is the ability to whitelist query-params instead, this way you may only retain what your application needs and not care when the next campaign doesn't use Google Analytics' utm_* parameters, they will be filtered out already.
