The destination resource can contain variables recognized by the routing service (currently only ACCOUNT variable is supported). The default value maps all the incoming topics into the ${ACCOUNT} (account name) URL.	.*,${ACCOUNT}

2) 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
