- added new function "util::join_location" as counterpart of "util::split_location" to use IP-literal notation when necessary (IPv6). The function can be used in connection with "util::split_location" to substitute hostnames/ports etc. in full urls instead of insecure regsub operations. - function "util::external_url_p": * don't use "string match" for comparing locations, since this will fail with IP-literal notation * no need to compare with encoded name (if needed, on should provide an option).
- proc get_referrer: add optional flag "-relative" to return the referrer without protocol and host +CVS: ----------------------------------------------------------------------
