Chapter 9 Advanced Expressions: String Sets, String Patterns, and Data Formats 161
To create a named pattern set using the AppExpert in the configuration
utility
1. In the navigation pane, expand AppExpert, and click Pattern Sets.
2. In the details pane, click Add.
3. In the Create Pattern Set dialog box, enter a name in the Name field, and
then click Add.
4. In the Add Pattern dialog box, enter a pattern in the Pattern field.
5. If you want to manually assign an index number to this pattern set, in the
Index field, enter an integer. Note that if you manually add an index to this
entry, you must do this for all entries in the set. Otherwise, the NetScaler
will automatically assign an index to each entry in the set.
6. Click Create.
7. Continue to add patterns, as needed, as described in the previous steps.
8. Click Create.
To add a pattern set to a policy expression using the configuration utility
1. In the navigation pane, click the name of the feature for which you want to
configure an advanced policy, for example, you can select Integrated
Caching, Responder, DNS, Rewrite, or Content Switching, and then
click Policies.
2. Click Add.
3. In the Create Policy dialog box for most features, instead of clicking
directly in the Expression field, click the Add icon (the plus sign). For
Content Switching, click Configure, click Advanced Syntax, and then
click the Add icon (the plus sign).
4. In the Add Expression dialog box, select the initial expression parameters
from the drop-down menus.
5. Select one of the “_ANY” or “_INDEX” operators (for example,
CONTAINS_ANY or EQUALS_INDEX). For more information about
pattern set operators, see the table, “Operators That Compare Text and
HTTP Headers With a Pattern Set,” on page 158.
