PATH.IGNORE_EMPTY_ELEMENTS This method ignores the empty elements in a list.
For example, if the delimiter in a list is “,” the
following list contains an empty element after the
entry “a=10”:
a=10,b=11, ,c=89
The element following b=11 contains a space and
is not considered an empty element.
Consider the following header:
Cust_Header : 123,,24, ,15
The following expression returns a value of 4 for
this header:
http.req.header("Cust_Header").
typecast_list_t(','). ignore_empty_
elements.count
The following expression returns a value of 5 for
the same header:
http.req.header("Cust_Header").
typecast_list_t(',').
VPN.CLIENTLESS_HOSTURL.
PATH_AND_QUERY Evaluates the portion of the URL that follows the

the preceding URL.
