Jeff,
I have the exact same problem under Solaris 9. I'm not sure if
this is related to the problem but I belive nsvhr should NOT
change the ``Connection'' header to ``close'' when poxying over
a unix domain socket (see line 621 of nsvhr.c).
In fact, I think what nsvhr over nsunix does ``proxying'' is a
bit of a streach since nsvhr merely passes the file descrptor of
the HTTP client to the apropriate nsd instance (along with the
headers).
We can probably use a far simpler program to do virtual hosting
over a unix domain socket. I wrote one just to get a site
working in only about 640 lines of code.
