Volume 9: Managing the Blue Coat SG Appliance

authenticate-401 attribute All transparent and explicit requests received on the port always use transparent

authentication (cookie or IP, depending on the configuration). This is especially

useful to force transparent proxy authentication in some proxy-chaining scenarios

authenticated content Cached content that requires authentication at the origin content server (OCS).

Supported authentication types for cached data include basic authentication and

IWA (or NTLM).

authentication Allows you to verify the identity of a user. In its simplest form, this is done through

usernames and passwords. Much more stringent authentication can be employed

using digital certificates that have been issued and verified by a Certificate Authority.

See also basic authentication, proxy authentication, and SSL authentication.

authentication realm Authenticates and authorizes users to access SG services using either explicit proxy

or transparent proxy mode. These realms integrate third-party vendors, such as

LDAP, Windows, and Novell, with the Blue Coat operating system.

authorization The permissions given to an authenticated user.

bandwidth class A defined unit of bandwidth allocation.

bandwidth class hierarchy Bandwidth classes can be grouped together in a class hierarchy, which is a tree

structure that specifies the relationship among different classes. You create a

hierarchy by creating at least one parent class and assigning other classes to be its

children.

bandwidth management Classify, control, and, if needed, limit the amount of bandwidth used by network

traffic flowing in or out of an SG appliance.

basic authentication The standard authentication for communicating with the target as identified in the

URL.

BCAAA Blue Coat Authentication and Authorization Agent. Allows SGOS 5.x to manage

authentication and authorization for IWA, CA eTrust SiteMinder realms, Oracle

COREid, Novell, and Windows realms. The agent is installed and configured

separately from SGOS 5.x and is available from the Blue Coat Web site.

BCLP Blue Coat Licensing Portal.

byte-range support The ability of the SG appliance to respond to byte-range requests (requests with a

Range: HTTP header).

cache An "object store," either hardware or software, that stores information (objects) for

later retrieval. The first time the object is requested, it is stored, making subsequent

requests for the same information much faster.

A cache helps reduce the response time and network bandwidth consumption on

future, equivalent requests. The SG appliance serves as a cache by storing content

from many users to minimize response time and prevent extraneous network traffic.

cache control Allows you to configure which content the SG appliance stores.
