+url32 : integer
+ This returns a 32-bit hash of the value obtained by concatenating the first
+ Host header and the whole URL including parameters (not only the path part of
+ the request, as in the "base32" fetch above). This is useful to track per-URL
+ activity. A shorter hash is stored, saving a lot of memory. The output type
+ is an unsigned integer.

+url32+src : binary
+ This returns the concatenation of the "url32" fetch and the "src" fetch. The
+ resulting type is of type binary, with a size of 8 or 20 bytes depending on
+ the source address family. This can be used to track per-IP, per-URL counters.
