Name of the pattern set to which to bind the string.
This is mandatory parameter.

String of characters that constitutes a pattern. For more information about the characters that can be used, refer to the character set parameter. Note: Minimum length for pattern sets used in rewrite actions of type REPLACE_ALL, DELETE_ALL, INSERT_AFTER_ALL, and INSERT_BEFORE_ALL, is three characters.
This is mandatory parameter.

Integer that identifies the string pattern within the pattern set. You can assign index values or allow them to be assigned automatically. If you specify an index for the first pattern that you bind to the set, you must do so for each subsequent pattern. If you do not specify an index for the first pattern, the Citrix ADC generates an index. If you subsequently specify an index when binding a pattern to the set, an error message appears. The pattern index of a matching pattern can be used within expressions. For example, HTTP.REQ.URL.EQUALS_INDEX("test_url").EQ(5), returns true if the request URL matches the strings in the test_url pattern set with index 5.
Minimum value = 1.
Maximum value = 0xFFFFFFFA.

Character set associated with the characters in the string. Note: UTF-8 characters can be entered directly (if the UI supports it) or can be encoded as a sequence of hexadecimal bytes '\xNN'. For example, the UTF-8 character 'ü' can be encoded as '\xC3\xBC'.
Possible Values : ASCII, UTF_8.
