Topic matching example
This is a topic matching example.
Please note that the incoming message use the JMS syntax (so the topic levels are . sepated instead of / separated)

(?:[^.]*?\.){2}topic1\.topic1_1,rest_path_1
(?:[^.]*?\.){2}topic2,rest_path_2
(?:[^.]*?\.){2}topic3\.topic3_1,rest_path_3

This configuration forwards the messages for all the account's clients to different destination topics depending on 3 semantic topics:

MQTT semantic topic	HTTP Endpoint
topic1/topic1_1	/rest_path_1
topic2	/rest_path_2
topic3/topic3_1	/rest_path_3
