SYS_T
Designates an expression that refers to the ApplicationSwitch,
rather than the client or server.
This topic lists the expressions that are provided by this class.
CHECK_LIMIT(text_tidentifier_name)
Used for rate limiting.
Returns a boolean Result.
Parameters(expressions not allowed):
identifier_name -
Identifier Name

Returns a boolean result.
Examples:
CLIENT_EXPR("client.av(Norton).exists")
add some more examples
Parameters(expressions not allowed):
s -
Client Expression
Returns: bool_at
ERROR

EVAL_CLASSIC_EXPR(classic_expr s)
Evaluate classic-style Citrix ADC expressions.
NOTE: use of Classic expressions is deprecated - use Default
(Advanced) expressions instead of this function.
The result of this evaluation can continued to be used
for further Advanced operations. This operation is intended to
be a bridge between traditional Citrix ADC expressions, which
we call "classic" expressions and the Advanced expressions. Both
inline and named classic expressions can be used as input.
Examples:
SYS.EVAL_CLASSIC_EXPR("ns_slowclient")
SYS.EVAL_CLASSIC_EXPR("REQ.SSL.CLIENT.CIPHER.BITS > 1000")
SYS.EVAL_CLASSIC_EXPR("url contains abc")
SYS.EVAL_CLASSIC_EXPR("REQ.IP.SOURCEIP == 10.102.1.61 -netmask 255.255.255.255")
SYS.EVAL_CLASSIC_EXPR("time >= *:30:00GMT")
SYS.EVAL_CLASSIC_EXPR("e1 || e2")
SYS.EVAL_CLASSIC_EXPR("REQ.HTTP.URLLEN > 50")
SYS.EVAL_CLASSIC_EXPR("dayofweek == wedGMT")

s -
Classic Expression
