The webserver for this port creates a script that will send triggers if accessed in a browser, to send the same triggers insert '/ajax/' into the url before the trigger ID.

Subject: HTTP Trigger Rename Button
I can rename a panel element in DashBoard, but the button on the HTTP Trigger Web Page does not rename.
Is this expected behaviour?
What I'm really trying to do is use a web api to revel parameters without having to wrote my own handler.
Does that already exist?
Thanks
