Citrix Systems Network Router 9.2 User Manual

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.
