Working with Clusters and Match Rules
Example Match Rules
The Related Topics navigate to examples of how to create a few of the most commonly used types
of match rules.
Parsing the URI Using Match Rules
In this example, we want to direct requests to a pool of specific server pools based on the
hostname used in the URI contained in the request. We want all requests for URIs that start with
“support” to go to one server pool, and all other requests that do
not match this rule to be load
balanced across all server pools in the cluster.
To do this, we will construct one match rule that parses the URI; if the URI contains the string
“support”
, it forwards the request to the server pool
sv_support
. For this example, we assume that
a cluster with server pools has already been defined.
1. Log into the GUI using a login that has add/del access for the cluster.
2. In the left frame, 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 a name into the
Match Rule Name
field. In this case
New Match Rule
was
added.
b. Select the
Next Match Rule
from the drop-down list to determine the placement
of
New Match Rule
in the order of processing. In this case
test
was selected.
c. Click on Commit . If test was selected as the Next Match Rule it will appear
beneath
Test
in the navigation pane on the left.
The match rule is created, added to the navigation pane on the left, and its Configuration tab is
opened. Refer to
"Using the Match Rule Expression Editor"
on page 409 for further descriptions on
using the Expression Editor.
3. Click on the Expression Editor button and drag and drop host_prefix from the drop-down box
in the
Functions
pane into the
Expression Workbench
pane.
4. Type “
support
” into the
hostname prefix
text box as follows:
