constant server connection

Hello all;

I have a page displaying status indicators for a number of systems. Statuses change often and unpredictably. I don’t want to refresh the page every 5 seconds in order to catch changes in status – I would rather *tell* the page that something has changed.

I designed the page such that relevant status areas are identifiable and can be dynamically re-written. What i’m interested in is some way to maintain a constant connection with the server.

My ideal solution would be some kind of control or applet that sits on a page and acts as a listenter, waiting to recieve command strings from the server. It could be as simple as an applet or other device that recieves a string and hands it off to a javascript handler to parse. It would be highly desirable for this object to be able to trigger a javascript handler and hand off to it the string it recoeved – the script could then parse the string and decide what to do on the page.

Any help or alternative solutions would be appreciated. I would be ok hitting the server in the background and returning a change list, as well…. but this is subject to latency issues etc. and I haven’t been able to get it to work properly.

Again, all help is appreciated.
