1. The host headers are for ISA's benefit and DNS's benefit, nothing to do with having them working. 2. No idea, but I wouldn't think so. -----Original Message----- From: Andrew English [mailto:andrew@xxxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, February 23, 2005 5:57 PM To: ISA Mailing List Subject: [isalist] RE: HTTP to HTTPS and HTTPS to HTTPS http://www.ISAserver.org Honestly Steve you shouldn't have to use host headers under Windows 2003 Server. I have 4 websites on my web server which work with nothing but IP's. My question about redirection, is there anyway to fool ISA into redirecting port 80 HTTP traffic to another server on the same name and letting RPC do its own thing when the right moment comes along?

Add another IP address on the exchange or IIS webserver, use that ip for the new site...give it a host headername....create the dns entry for it.....create a publishing rule for it....hey presto it works. <snip> The haggis is unusual in that it is neither consistently nocturnal nor diurnal, but instead is active at dawn and dusk (crepuscular), with occasional forays forth during the day and night.
