Greetings!

I have a generic code which instantiates a HTTPRequest as a child node. When the child node finishes the http request, it emits the “request_completed” signal, which runs the appropriate function its attached to and passes the html body as a function parameter into that function. How can I get the html body from the signal function back to the parent node which instantiated the HTTPRequest?
