Normally running the "Default Rule" for caching, as it suits my needs just fine. I did create and additional one yesterday that was basically the same except for the option "Never, no content will every be cached" was turned on. I haven't run any captures yet, requested a secretary in an outer building to test it out again today when she has time to see if the reboot helped. -----Original Message----- From: Jim Harrison [mailto:Jim@xxxxxxxxxxxx] Sent: Wednesday, February 09, 2005 10:07 To: [ISAserver.org Discussion List] Subject: [isalist] RE: Weird caching problem. http://www.ISAserver.org What caching rules do you have in place? Have you run captures to see what the difference is between the two deliveries?
