AASX Connect enables a simple publish and subscribe via REST.
AASX Server can connect to an AASX Connect and an AASX Connect can connect to another AASX Connect. By this a tree of connects can be built.
The REST communication is company proxy/firewall friendly. It uses only an inside-out communication.
A ready to use connect is running on http://admin-shell-io.com:52000. AASX Server connects to this by the option "--connect". This is used for I40 Language and for Publish/Subscribe in AASX Server.
Please take a look on TestConnect and let this run to better understand AASX connect.
