5. Click on accept after entering “ support ” and then click on the continue button at the bottom of
the
Expression Editor
to save the expression.
Now, all requests for URIs that start with “ support ” should go to the sv_support server pool, and all
other requests that do not match this rule to be load balanced across all server pools in the
cluster.
Changing Persistence Settings Using Match Rules
By default, a client request that matches a match rule expression is load balanced using the same
load balancing parameters and options that are currently set on the cluster. The following
describes how to change load balancing parameters and flags in a match rule.
For example, persistent connections to server pools are enabled by the Persist cluster flag, which
is enabled by default when you create a cluster. Let’s assume that you only want to disable
persistence for incoming requests that have a URI containing a hostname in the following format:
xxx.testdonotpersistexample.com
We’ll use the
host_suffix()
match rule function to test for the above hostname format. For this
example, we assume that a cluster with three server pools has already been defined. We will
construct a match rule that will turn off
Persist for any request that contains the host suffix
“
testdonotpersistexample.com
”; this request will be balanced across all of the server pools in the
cluster.
1. Log into the GUI using a login that has
add/del
access for the cluster.
2. In the navigation pane on the left, right-click the name of the Layer 7 cluster to which you
want to add the rule, and select
Add Match Rule
. The
Add Match Rule
dialog appears:
a. Type
nopersist
into the
match name
text box.
