Is it possible to do a HTTP post from a Processing program?

[TeppoTee]

I’ve been a Processing heavy user for years. Among other things have used loadString() quite a lot to fetch information from web server(s) . Is there a counterpart to loadStrings() which would allow me to do a HTTP post to (my own) webserver? I looked in the documentation and saveStrings doesn’t seem to support the use of URL parameters.

Or, should I just start learning P5*js? I’m afraid the latter is true

I’m using the HTTP Request library from Dan Shiftman. The issue, i think, is when I use post.addData it requires…
