False filter


You can use the False filter to force a path in the policy to return false. This can be useful to create a false positive path in a policy.

The following policy parses the HTTP request and then runs a Message Size filter on the message to make sure that the message is no larger than 1000 bytes. To make sure that the message cannot be greater than this size, you can connect a False filter to the success path of the Message Size filter. This means that an exception is raised if a message exceeds 1000 bytes in size.
