One idea we have bee working on here at S&M, is to convert the 5250 stream
on the fly to JSON and create a super thin java-script client that works
like what we like to calling reverse AJAX.

Reverse AJAX is normally AJAX where the request is what the 5250 stream
normally reads on READ or EXFMT I/O

By using JSON it will ultimately gives you the possibility to enhance the
5250 stream by joining extra attributes/values with user exits program.

Screen scraping on steroids ... does it make sense guys??

I will not be getting anything done on my honey-do
list ... thanks a lot Pete ;-)

It's not worth it. Take care of the honey-do list, first. Now that I've
begun with marital advise, I'll suggest something for web5250.

The sign-on screen is 23K of HTML. That just won't cut it. An HTML stream
that's 20 times bigger than its corresponding 5250 stream will eat your
server's CPU and clog your bandwidth. So my suggestion would be to have the
server output something more like a 5250 data stream, and have a
light-weight JavaScript client convert it to DOM elements at runtime.

Something is puzzling me about the server component, too. If it's based on
the tn5250j client, how does each user get their own separate session?

Nathan.
