Important

Packet prioritization using DiffServ works in networks whose routers support Quality of Service (QoS) functionality.
Uniform Resource Locator (URL) priorities listed on the URLs tab will be used by ISA Server to apply DiffServ bits for content that can be inspected by ISA Server (content that has not been tunneled). Content that has been tunneled over HTTPS cannot be inspected, and the URL cannot be known, so ISA Server will apply DiffServ bits to domains, which you specify on the Domains tab.
Use an asterisk (wildcard character) at the end of the URL, unless you want to assign a priority only to a specific URL.
After you add URLs, you can use the UP ARROW and DOWN ARROW keys to order them. This allows you to apply priorities to specific URLs. If a more general URL precedes a specific URL, the specific URL will never be matched.
For example, you may want to apply a high priority to www.contoso.com/news/*, and a lower priority to www.contoso.com/*. For the priorities to be applied correctly, www.contoso.com/news/* must be higher on the list. Otherwise, the /news/* request will get to the www.contoso.com/* entry and have the lower priority applied before the /news/* entry is reached.
