Configuring Generic Parameter Maps
Generic parameter maps allow you to specify nonprotocol-specific behavior for data parsing. Generic
parameter maps examine the payload and make decisions regardless of the protocol.
Use this procedure to configure a generic parameter map.
Boolean Functions:
$http_query_param_present(query-param-name)
$http_query_param_notpresent(query-param-name)
$http_cookie_present(cookie-name)
$http_cookie_notpresent(cookie-name)
$http_header_present(request-header-name)
$http_header_notpresent(request-header-name)
$http_method_present(method-name)
$http_method_notpresent(method-name)
Evaluates to a Boolean value: True or False, depending on the
presence or absence of the element in the request. The elements are
a specific query parameter (query-param-name), a specific cookie
(cookie-name), a specific request header (request-header-name), or
a specific HTTP method (method-name). All identifiers are
case-sensitive except for the HTTP request header name.
$regex_match(param1, param2) Evaluates to a Boolean value: True if the two parameters match and
False if they do not match. The two parameters can be any two
expressions, including regular expressions, that evaluate to two
strings. For example, this function:
$regex_match($http_query_param(URL), .*Store\.asp.*)
compares the query URL with the regular expression string
.*Store\.asp.*
If the URL matches this regular expression, this function evaluates
to True.
