[Koha] multiple public Z39.50 on the same server

[Barton Chittenden]

Magnus,

I think that your solution will work for SRU, because it uses http as its
transport layer protocol -- but I'm not so sure that z39.50 will be able to
differentiate host names. My guess is that different ports will be
required... but my certainty level is somewhere between 'wild ass guess'
and 'educated guess', so take that for what it's worth.
