Glossary

cookie header

One of Equalizer's supported headers, a cookie header is an HTTP data string previously sent by a server that is

stored in Equalizer for future routing.

cookie persistence

In cookie-based persistence, Equalizer "stuffs" a cookie into the server's response header on its way back to the

client. This cookie uniquely identifies the server to which the client was just connected. The client includes

(sends) the cookie in subsequent requests to the Equalizer. Equalizer uses the information in the cookie to route

the requests back to the same server.

cookie switching

Refers to three distinct ways to perform cookie switching: cookie-read, cookie-insert, and cookie-rewrite.

daemon

An application that runs in the background and performs one or more actions when events trigger those actions.

default gateway

A default gateway is on the same subnet as Equalizer, and is the gateway which Equalier relies on to route

traffic.

delay weight

The relative influence on the policy of the current response time between Equalizer and the server.

Direct Server Return (DSR)

In a Direct Server Return (DSR) configuration, the server receiving a client request responds directly to the

client IP, bypassing Equalizer. Because Equalizer only processes incoming requests, cluster performance is

dramatically improved when using DSR in high bandwidth applications, especially those that deliver a significant

amount of streaming content. In such applications, it is not necessary for Equalizer to receive and examine the

server’s responses: the client makes a request and the server simply streams a large amount of data to the

client.

DNS

Domain Name System or Domain Name Service; used to map domain names to Internet servers in order to link to

IP addresses or map IP addresses to domain names. See IP address.

DNS TTL

The amount of time, in seconds, that a name server is allowed to cache the domain information. See DNS and

TTL.

domain

The highest level in an IP address and the last part of the address in the URL. The domain identifies the category

under which the Web site operates. For example, in www.coyotepoint.com, com is the domain, where com

represents a commercial site. See domain name, IP address, and subdomain. See also DNS.

domain name

The owner of an IP address. The next highest level in an IP address and the next-to-last part of the address. For

example, in www.coyotepoint.com, coyotepoint is the domain name. See domain, IP address, and subdomain.
