Defined in packages/acs-core/utilities-procs.tclLike ns_conn location - Returns the location string of the current
request in the form protocol://hostname[:port] but it looks at the
Host header, that is, takes into account the host name the client
used although it may be different from the host name from the server
configuration file. If the Host header is missing or empty util_current_location
falls back to ns_conn location.
