It could work for prefix equality (with a keyed hash function like
siphash to avoid collision forgery), though hashing every URL
(possibly multiple times, for each different configured length) might
be more costly than the current strncmp.
But I suppose that the main issue is for regex matchings ("ProxyPass
~" and ProxyPassMatch)...
