Match expressions can be combined using Boolean AND, OR, and NOT operators to form
more complex rules.
Defining a Match Rule
By default, all clusters have a single match rule that matches ANY and matches all servers.
To add a match rule to an HTTP or HTTPS virtual cluster:
1. Log into the Equalizer Administration interface with edit access.
2. In the left frame, click the name of the cluster to which you want to add the rule.
3. Select Add Match Rule from the local menu in the Cluster Parameters frame. The
Create New Match Rule dialog is displayed in the right frame.

■
Host header suffix—the suffix of the host to which the request was sent. For
example, “somesite.com”. (The value of the host header suffix is extracted from
the contents of the
Host
header in the request.)
■

and the file name. For example,”
/somedir/somepage.html
”.
■
