I'm pretty familiar with jQuery so it is rather easy

You really should try the IRC example in

https://github.com/joearms/ezwebframe/blob/master/demos/chat/chat2.html

This is 145 lines of code in total - this is *everything* the neat thing
is that the program that manages the interface is also the IRC server
there is only one process involved.

but from a remote point of view it is an IRC server in a web page :-)

I don't know if you've tried this:

On machine one - note your IP adress (suppose it's 223.45.12.34)
start ezwebframe and go to localhost:1456 and open the chat2.html page

Open your firewall (if you have one) to allow remote access to port 1456

Go to any other machine on the planet and go to

http://223.45.12.34:1456

And it all works.

I've tried this on several machine and it works fine. When I get time I'll
open up my firewall and we can try this (not today, I'm busy)

I'd recommend anybody who has downloaded the code to try this to get the
wow feeling.

I was amazed that it worked so easily and was so short.

I wrote this to update the chapter on IRC in my book - and found that an
entire
chapter vanished down to one page after I made the interface to web sockets.

I think the key point is uniform messaging - the IRC server AND the web
server are the same process and all they see are uniform messages (in this
case JSON) - to get the browser to do things you send it JSON messages.
When things happen in the browser you get sent JSON messages.

The point is the bits fit together nicely - conceptual integrity rules.
