Prefix	Description
HTTP.REQ.USER.EXTERNAL_	Returns a list of all the external groups to which the user
GROUPS(sep)	belongs. The groups are separated by the given
	delimiter.
	For example, the following expression gives a list of all
	the external groups, and the groups are separated by a
	colon (":"):
	HTTP.REQ.USER.EXTERNAL_GROUPS(':')
	Parameters:
	sep - delimiter
HTTP.REQ.USER.EXTERNAL_	Ignores the empty elements in the list of external groups
GROUPS.IGNORE_EMPTY_	to which the user belongs.
ELEMENTS	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 following "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.GROUPS	Returns a list of the internal and external groups to
	which the user belongs. The groups are separated by a
	comma (",").
	In this list, internal groups are listed first, followed by
	external groups.
