Displaying data in real-time on web page [closed]

Answer 1

The term is Comet, and it's basically just a block of code setup to run forever and poll (send an HTTP request) at intervals to get new data back, if any, populating an existing area with the new data.

You can read more about it:

Stackoverflow question with an example:

• How do I implement basic "Long Polling"?

Answer 2

If you are planning to use javascript, then you will probably have a timer class that every so often it will fetch an update using ajax.

Answer 3

That sort of problem has always two types of solution: poll or push.

You can poll using AJAX techniques OR have a long-lived connection to a server pushing data to the client (COMET).
