Subject: net/http bad header patch

Ran into a web server with a broken header. Unfortunately, it's not one 
I have control of so I can't fix it. This problem seems to be ignored 
by the browsers I've tried, but not Net::HTTP. Here's what the header 
looks like,

HTTP/1.0 200 OK
Connection: close
Server: Microsoft-IIS/5.0
Date: Fri, 08 Jul 2005 01:06:34 GMT
Expires: Fri, 08 Jul 2005 11:06:34 GMT

This causes Net::HTTP to raise a Net::HTTPBadResponse. The quick fix 
patch.
