I created a webserver using the Indyhttppserver component. The clients use |
mostly IE and Firefox to connect and send requests to which the server
reply. What I would like to do is have a live connection to the server so
that whenever the server processes new data received from a coms port I want
to display that data on the clients webbrowser without having to refresh the
page.
I hope it makes sense now.
Thanks

The HTTP protocol is not designed for that. It is a command/response
protocol, not a streaming push protocol. Refreshing the page periodically
is the only way for a browser to get the latest HTML from the server.
Otherwise, you will have to write a Java applet that runs on the web page
and maintains its own persistent connection to the server. The applet can
then alter the client-side HTML dynamically in code. Or else look at using
RSS feeds instead to present your COM port data in a dynamic manner.
