expressions and policies, be sure you understand the relevant NetScaler feature
and the structure of your data, as follows:
You may want to run
a trace on the type of traffic or content that you want to configure. This will
give you an idea of the parameters and values, and operations on these
parameters and values, that you need to specify in an expression.
Note: The NetScaler supports either classic or default syntax policies
within a feature. You cannot have both types in the same feature. Over the past
few releases, some NetScaler features have migrated from using classic policies
and expressions to default syntax policies and expressions. If a feature of
interest to you has changed to the default syntax format, you may have to
manually migrate the older information. Following are guidelines for deciding
if you need to migrate your policies:
- If you configured classic
policies in a version of the Integrated Caching feature prior to release 9.0
and then upgrade to version 9.0 or later, there is no impact. All legacy
policies are migrated to the default syntax policy format.
- For other features, you need
to manually migrate classic policies and expressions to the default syntax if
the feature has migrated to the default syntax.
