HTTP.REQ.USER.EXTERNAL_
GROUPS(sep) Returns a list of all the external groups to which the user
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_
GROUPS.IGNORE_EMPTY_
ELEMENTS
Ignores the empty elements in the list of external groups
to 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 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.
