Volume 9: Managing the Blue Coat SG Appliance
| 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 |
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 |
| LDAP, Windows, and Novell, with the Blue Coat operating system. |
authorization | The permissions given to an authenticated user. |
B |
|
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. |
The ability of the SG appliance to respond to | |
| Range: HTTP header). |
C |
|
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. |
