from what i know of this, the reason HTTP works with virtual
domains is because the recent web browsers know to send a HOST:
mime header with their requests to the http servers. older web
browsers don't include any such HOST: field, and so wind up
getting the default domain for whatever IP they're requesting
from. (serensoft.com -- to use my example -- serves
dontUthink.com and others; without the HOST: field, my server
will never know to delve into the dontUthink.com document tree,
and would return serensoft.com stuff by default.)
so postgres would then <if guess is correct> need to accomodate
the mime fields in a similar fashion, and clients would need to
generate them, likewise.
probably.
