Volume 9: Managing the Blue Coat SG Appliance

trial period	Starting with the first boot, the trial period provides 60 days of free operation. All
	features are enabled during this time.
U
unicast alias	Defines an name on the appliance for a streaming URL. When a client requests the
	alias content on the appliance, the appliance uses the URL specified in the unicast-
	alias command to request the content from the origin streaming server.
universal time coordinates	An SG appliance must know the current UTC time. By default, the appliance
(UTC)	attempts to connect to a Network Time Protocol (NTP) server to acquire the UTC
	time. If the SG appliance cannot access any NTP servers, you must manually set the
	UTC time.
URL filtering	See content filtering.
URL rewrite rules	Rewrite the URLs of client requests to acquire the streaming content using the new
	URL. For example, when a client tries to access content on www.mycompany.com,
	the appliance is actually receiving the content from the server on 10.253.123.123. The
	client is unaware that mycompany.com is not serving the content; however, the
	appliance access logs indicate the actual server that provides the content.
W
WCCP	Web Cache Communication Protocol. Allows you to establish redirection of the
	traffic that flows through routers.
Web FTP	Web FTP is used when a client connects in explicit mode using HTTP and accesses an
	ftp:// URL. The SG appliance translates the HTTP request into an FTP request for the
	OCS (if the content is not already cached), and then translates the FTP response with
	the file contents into an HTTP response for the client.
Websense log type	A Blue Coat proprietary log type that is compatible with the Websense reporter tool.
X
XML responder	HTTP XML service that runs on an external server.
XML requestor	XML realm.
