Example Match Rules
Equalizer Installation and Administration Guide 141
In this example, we assume that we can determine this by examining the hostname used in incoming
requests. Any request containing a hostname in the following format will not require a persistent
connection:
name.testexample.com
We’ll assume that any request with a hostname having the format name.testexample.com will not
require persistent connections. We’ll use the host_suffix() match rule function to match the
hostname. For this example, we assume that a cluster with three servers (sv00, sv01, sv02) has
already been defined. We will construct a match rule that turn off persist for any request that
contains the host suffix “testexample.com”; this request will be balanced across all three servers in
the cluster.
