Hi Glen,
For reverse proxy, the ISA Server respects the expiration settings
configured on the Web server.
HTH,

Subject: [isalist] ISA DNS SLOWDOWN/LATENCY
http://www.ISAserver.org
I've been publishing a web server via ISA for about a year now, however,
this recent occurrence has me perplexed...
The server seems to only be UPDATING every 7-10 minutes... Among other
things, the website features a FEEDBACK/DISCUSSION board... In the past,
when someone posts to the board, their message appeared immediately....
For the past week, the messages posted to the published server are
drastically DELAYED, sometimes up to 7-10 minutes.. If I'm LOCAL on the
network, I see the messages IMMEDIATELY, but to the OUTSIDE WORLD, the
messages only post after a while..
The discussion/HTML linkages are all working fine... BUT there is
latency
SOMEWHERE between the ISA SERVER, and the internal server where the
FEEDBACK
BOARD is housed...
I have all Service PACKS (1) installed, I am using a DNS resolution
service
(TZO), however, the latency is still present even when I access the
board
via IP ADDRESS, HOST HEADER is sent by USER; I'm not changing it...
I even REMOVED ISA from the equation for a few minutes, and ALLOWED THE
OUTSIDE WORLD to hit this SERVER DIRECTLY... The postings were
AUTOMATIC...
I don't want to SERVER PUBLISH this, because I NEED port 80 going
OUTBOUND...
Any ideas are appreciated...
