HTTP Expression Prefixes that Return Text

Prefix	Description
HTTP.REQ.USER.GROUPS.	Ignores the empty elements in the list of groups to
IGNORE_EMPTY_ELEMENTS	which the user belongs.
	If the element delimiter in the list is a comma (","), then
	the following list has an empty element following
	"a=10":
	a=10,,b=11, ,c=89
	But the element that follows "b=11" is not considered
	an empty element.
	For example, consider the following header in an HTTP
	request packet:
	Cust_Header : 123,,24, ,15
	The following expression returns a value of 4:
	HTTP.REQ.HEADER("Cust_Header").TYPECAST_
	LIST_T(','). IGNORE_EMPTY_ELEMENTS.COUNT
	The following expression returns a value of 5:
	HTTP.REQ.HEADER("Cust_Header").TYPECAST_
	LIST_T(',').COUNT
HTTP.REQ.USER.	Returns a list of groups to which the user belongs. The
GROUPS(sep)	groups in the list are separated by the delimiter
	specified as the argument.
	For example, the following expression returns a colon-
	separated list of all the groups to which the user
	belongs.
	HTTP.REQ.USER.GROUPS(':')
	In this list, internal groups are listed first, followed by
	external groups.
	Parameters:
	sep - delimiter
