The URL lists are used in rules that ISA uses to process requests. If the request is blocked by policy rules then it never gets out of the ISA, consequently no content is returned. This would not be the case with content filtering, however. This by nature requires content be returned to the ISA in order for it to check against it policy configuration. -Shawn ----- Shawn R.

My question is that if these ads feteched from their respective sites but are blocked by ISA to eneter the inside network or no request is sent to the blocked ADs sites and so they are not feteched. If the former is yes, then ISA does not help in saving the bandwidth used for internet access rather it saves bandwidth of the inside network- LAN. Please someone clarify this point. ------------------------------------------------------ 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: shawn.quillman@xxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=isalist Report abuse to listadmin@xxxxxxxxxxxxx
