UDP

See User Datagram Protocol (UDP).

Uniform Resource Locator (URL)

The address of a resource on the Internet. A common URL syntax has the form protocol://host:port/path, where protocol specifies the means of returning the object, such as Hypertext Transfer Protocol (HTTP) or File Transfer Protocol (FTP); host specifies the remote server where the resource (file) resides; port (optional) specifies the port number to which to connect; and path specifies the path to the resource (file) on the remote server.

upstream routing

The routing of a response from one Forefront TMG computer to another Forefront TMG computer. A request from a client computer always flows upstream to Forefront TMG computers until the requested item is found, whether it is in the cache of a Forefront TMG computer or from the Internet. Forefront TMG sends the response downstream to the client computer.
