101
R
real-time streaming protocol
(RTSP)
A standard method of transferring audio and video and other time-based media over
Internet-technology based networks. The protocol is used to stream clips to any RTP-
based client.
reflect client IP attribute
Enables the sending of the client's IP address instead of the SG's IP address to the
upstream server. If you are using an application delivery network (ADN), this setting
is enforced on the concentrator proxy through the Configuration > App. Delivery
Network > Tunneling tab.
registration An event that binds the appliance to an account, that is, it creates the Serial#, Account
association.
remote authentication dial-
in user service (RADIUS)
Authenticates user identity via passwords for network access.
reverse proxy A proxy that acts as a front-end to a small number of pre-defined servers, typically to
improve performance. Many clients can use it to access the small number of
predefined servers.
routing information protocol
(RIP)
Designed to select the fastest route to a destination. RIP support is built into Blue
Coat appliances.
router hops The number of jumps a packet takes when traversing the Internet.
S
secure shell (SSH) Also known as Secure Socket Shell. SSH is an interface and protocol that provides
strong authentication and enables you to securely access a remote computer. Three
utilities—login, ssh, and scp—comprise SSH. Security via SSH is accomplished using
a digital certificate and password encryption. Remember that the Blue Coat SG
appliance requires SSH1. An SG appliance supports a combined maximum of 16
Telnet and SSH sessions.
serial console A third-party device that can be connected to one or more Blue Coat appliances.
Once connected, you can access and configure the appliance through the serial
console, even when you cannot access the appliance directly.
server certificate categories The hostname in a server certificate can be categorized by BCWF or another content
filtering vendor to fit into categories such as banking, finance, sports.
server portals Doorways that provide controlled access to a Web server or a collection of Web
servers. You can configure Blue Coat SG appliances to be server portals by mapping a
set of external URLs onto a set of internal URLs.
server-side transparency The ability for the server to see client IP addresses, which enables accurate client-
access records to be kept. When server-side transparency is enabled, the appliance
retains client IP addresses for all port 80 traffic to and from the SG appliance. In this
scheme, the client IP address is always revealed to the server.
service attributes Define the parameters, such as explicit or transparent, cipher suite, and certificate
verification, that the SG appliance uses for a particular service. .
