I'm looking for confirmation that: include $fn; is an allowed form of the include statement. > While it's certainly possible to rig up something using sockets, I don't > think that's how AJAX works, and you'd need a JS library that did. Hmmm, I think perhaps I've not made myself clear - sorry about that. At present I'm using AJAX and apache; I'd like to *stop* doing that (and not use another web server, either). In my case, client and server are the same machine - the user's machine. There is a browser window and JavaScript within it which makes the AJAX requests. I just happen to use apache to have a variety of PHP scripts run to provide results back to the browser window. > Generally, you should only really need to dynamically replace parts of a > long-running program if you don't want to restart it.

If these little scripts are merely responding to AJAX > requests, they should be really short-lived. At present these scripts generally are short-lived, but with some notable exceptions. Hence my exploration of whether I could use websockets instead. -- Cheers -- Tim
