calculate OPACBaseURL instead of using syspref
Calculate OPACBaseURL from the
CGI environment variables instead of using the
system preference. As a result of this patch,
it should be possible to change the hostname,
protocol, or port of the OPAC without having to
reset a system preference.
Also added a FIXME to opac/unapi - the URL of
the SRU/W server has no necessary relationship
to the URL of the OPAC.
Once this patch is confirmed, the syspref can
be removed.
