VPN.BASEURL.HOSTNAME.SERVER

Evaluates the server portion of the host name.

For example, if the host name is www.
mycompany.com or www.mycompany.com:8080, 
the server is www.mycompany.com. 

All text operations after this prefix are case 
insensitive.

VPN.BASEURL.PATH

Extracts a slash- (/) separated list from the path 
component of the URL. For example, this prefix 
extracts /a/b/c/mypage.html from the following 
URL:

http://www.mycompany.com/a/b/c/mypage.
html?a=1 

The following expression selects just the “a”:

http.req.url.path.get(1)

For more information on the GET operation, see 

VPN.BASEURL.PATH.IGNORE_

EMPTY_ELEMENTS

This prefix ignores the elements in a list. For 
example, the following comma-separated list has 
an empty element after “a=10”:

a=10,,b=11, ,c=89 

The element following b=11 contains a space, and 
by default, is not considered an empty element. 

Consider the following HTTP header:

Cust_Header : 123,,24, ,15 

The following expression returns a count of 4 
when evaluating this header:

http.req.header("Cust_Header").

typecase_list_t(',').ignore_empty_

elements.count 

The following expression returns a count of 5 
when evaluating this header:

http.req.header("Cust_Header").

typecase_list_t(','). count 

VPN.BASEURL.PATH_AND_QUERY

Evaluates the text in the URL that follows the host 
name. 

For example, if the URL is http://www.
mycompany.com/a/b/c/mypage.html?a=1, this 
prefix evaluates /a/b/c/mypage.html?a=1.
