Yes. -----Original Message----- From: isapros-bounce@xxxxxxxxxxxxx [mailto:isapros-bounce@xxxxxxxxxxxxx] On Behalf Of John T (lists) Sent: Tuesday, May 08, 2007 12:56 PM To: isapros@xxxxxxxxxxxxx Subject: [isapros] How to programmicly add IP address to a computer set I know that GFI WebMonitor3 if configured to use the Yahoo Adult list is able to block access to a site listed on Yahoo's adult site list by adding that site to the destination set WebMonitor3 created for use in the Deny Access Rule WebMonitor3 created. Is it possible to create a function that will resolve a URL to an IP address, compare that IP address to an existing list, if the IP is not on the list, add it to a computer set destination set on ISA 2006 Standard?
