Warning:

Q and S prefixes are deprecated from NetScaler 12.0 build 56.20 onwards and as an alternative, Citrix recommends you to use the HTTP.REQ and HTTP.RES functionality. However, Q and S prefixes are removed and no longer available on the Citrix ADC appliance release 13.1 onwards. For more information, see Advanced policy expression topic.

The following table is a listing of default syntax expression prefixes, with cross-references to descriptions of these prefixes and the operators that you can specify for them. Note that some prefixes can work with multiple types of operators. For example, a cookie can be parsed by using operators for text or operators for HTTP headers. For more information, see Expression Prefixes for text in HTTP requests and responses topic.

You can use any element in the following tables as a complete expression on its own, or you can use various operators to combine these expression elements with others to form more complex expressions.

Note: The Description column in the following table contains cross-references to additional information about prefix usage and applicable operators for the prefix.

For more information, refer Expression PDF to view the table.
