and converts it to an integer value. This can be used for session stickiness
based on a user ID for example, or with ACLs to match a page number or price.
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.
