Typecasting Operations

Operation	Description
text.TYPECAST_HTTP_	Converts the designated text to a multi-line HTTP header
HEADER_T("name")	that you specify in a name argument.
	For example, the following expression converts
	“MyHeader” to “InHeader”:
	http.req.header("MyHeader").typcast_http_
	header_t("InHeader")
	Typically, text operations that you specify in this type of
	expression apply to only the last line of this header, with
	some exceptions. For example, the CONTAINS operation
	operates on values in all the lines in instances of this header
	type.
text.TYPCAST_COOKIE_	Treats the designated text as an HTTP cookie as it appears in
T	a Set-Cookie or Set-Cookie2 header. You can apply name-
	value list operations as well as text operations to the
	designated text. For example, you can designate an equals (=
	) as the name-value delimiter and the semicolon (;) as the list
	element delimiter.
	If you apply name-value list operations, note that the list is
	parsed as if IGNORE_EMPTY_ELEMENTS were in effect.
	Each cookie begins with a cookie-name=cookie-valuepair,
	optionally followed by attribute-value pairs that are
	separated by a semicolon, as follows:
	cookie1=value1;version=n.n;value;domain=
	value;path=value
	If the same attribute appears more than once in a cookie, the
	value for the first instance of the attribute is returned.
number.TYPECAST_	Transforms the number to a value of data type “double”.
DOUBLE_AT
number.TYPECAST_IP_	Converts the number to an IP address.
ADDRESS_AT
number.TYPECAST_	Converts the number to time format.
TIME_AT
