They both resolve to the same IP address when resolved from the client. Possibly the difference is that the www one is the one that is "published" in the ISA server. Since this is on a separate internal network (different NIC in ISA server), it has to pass through the ISA server no matter what. I have one rule that allows "all protocols" between those two networks, and that is the one the logs show it is hitting and passing through. I'll try and test this out again today. I had noticed that yesterday the CPUs were running at 50-60% utilization most of the day, and there was almost 4GB of memory in use. This was not quite right, so I rebooted the server last night and now it is running at 5-10% utilization and only 1.8GB of memory in use, which is where it normally runs. It's possible something was hanging... -----Original Message----- From: Jim Harrison [mailto:Jim@xxxxxxxxxxxx] Sent: Wednesday, February 09, 2005 00:33 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Weird caching problem. http://www.ISAserver.org 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. -----Original Message----- From: Ball, Dan [mailto:DBall@xxxxxxxxxxx] Sent: Tuesday, February 08, 2005 10:34 AM To: [ISAserver.org Discussion List] 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 Computers on one subnet get the current version of a web page, while computers on another subnet get an older, outdated version.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? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx All mail to and from this domain is GFI-scanned. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: World of Windows Networking: http://www.windowsnetworking.com Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: dball@xxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx
