Great! I'll check it out. Thanks for your prompt response.

EDIT: Okay! This looks good. I found the Logic Editor for sending GET and POST requests to the server.

What if I want to go the other way and have the server notify the app of something? (Say, that a new resource is ready to load?)

Hello! I have a quick question about Blend4Web's features.

Similar to https://www.blend4web.com/en/forums/topic/758/, I'd like to write an application that lets the user change some values to modify an object mesh, and then either

a) communicates to the server what values the user specified, or
b) sends the modified mesh to the server.

Is either of these options possible with blend4web now?

Thanks!
Andrew
