BQOD:
What IP does:
"hostname"
And
"www.domain.org"
..resolve to?
If the internal client can reach either of them without speaking to ISA,
it won't use the ISA cache.

Subject: [isalist] Weird caching problem.
http://www.ISAserver.org
I saw a weird problem today with caching of our web server. Computers
on one subnet get the current version of a web page, while computers on
another subnet get an older, outdated version.
After talking to them a bit, they said it happens all the time, and it
usually takes a day for them to see the changes they made. If I use the
hostname of the web server computer as the URL
(http://hostname/webpage.htm), the current page comes up, but if I use
the published URL (http://www.domain.org/webpage.htm) of the same page,
it shows the old version.
I did the usual, cleared the Internet Explorer cache, searched the
entire hard drive for other cached copies, restarted IE, etc.., to
verify it wasn't the client that was caching it.
I checked the ISA logs, and it said the web request for that page was
passing right through to our webserver, from one subnet to the other.
I created a caching rule on the ISA server to "Never cache any content"
to see if that was the problem, didn't make a difference.
I changed the expiration date on the webserver for pages to expire
immediately and restarted IIS, didn't make a difference.
Anyone have any other ideas where to look?
