Hi,
I was about to give up posting this question at this group as no one
responded, so I though there was no one knowledgeable about this here. I
see that Kristofer Gafvert responded to a recent post about Host Headers so
I still have hope I can strike up a dialog.
My main concern with posting this question is that I am seeing IIS log
records for my web site that has a domain name in the cs-host field that
does not resolve to my IP address. I also see some records that have a NULL
value in this field. I am trying to understand how this could happen. Any
description or even URLs that point to a description that would help me
understand this would be appreciated.
