2.Associate a pattern with the named pattern set, as follows:

bind policy patset pattern_name pattern

Where pattern_name is the name of a pattern that you want to configure and pattern is an actual text pattern. Following is an example:

add policy patset myPatSet

bind policy patset myPatSet aaa bind policy patset myPatSet bbb bind policy patset myPatSet ccc

3.To view the named pattern set and its associated patterns, enter the following command:

show policy patset pattern_name

Where pattern_name is the name of a pattern that you want to view.

4.Configure the pattern set as part of an expression in a policy.

For more information, see “Creating or Modifying an Advanced Policy,” on page 14. Following is an example that uses the pattern set myPatSet, and returns TRUE if the value of the HTTP header named myHeader contains any of the strings that you defined earlier in this procedure:

add cache policy testPatSet -rule http.req.header("myHeader").contains_any("myPatSet") -action cache

To configure and use an index-based pattern set using the NetScaler command line

1.At a NetScaler command prompt, type:

add policy patset patternName

Where pattern_name is the name of a pattern that you want to configure.

2.Associate a pattern and an index with the named pattern set, as follows:

bind policy patset patternName pattern -index number

Where patternName is the name of a pattern that you want to configure, pattern is an actual text pattern, and number is the index value. Following is an example:

add policy patset myPatSet1

bind policy patset myPatSet1 aaa -index 1 bind policy patset myPatSet1 bbb -index 5 bind policy patset myPatSet1 ccc -index 4
