content-type must be set to
application/x-www-form-urlencoded to process the field names in
If this rule is applied to an agent configuration, only URL query string parameters are compared, because the agent does not receive the request body for processing.

Values entered here will be URL-encoded prior to the comparison. For example, if the value specified in the Value field is
v1 v2, when the engine performs the comparison, this value will convert to
v1%20v2before the search is performed.
- If additional parameters pairs are needed, click Add Row to add an additional row, then repeat steps 5-6.
- If the values should be an exact match to the value case, select the Case Sensitive check box.
If access is not allowed when a match is found, select the
Negate check box.
Ensure that the field name you enter is spelled correctly and exists. If you enter a field name that does not exist and you select Negate, the rule will always succeed. The Negate control applies to the entire set of conditions specified, and passes the rule if any condition is not met.
