A couple of options spring to mind. You could use a META refresh to reload the page every so often. It's a little clumsy, but widely supported, and easy to add. The downside is that reloading the entire page is likely to interrupt the user's concentration. I've seen some browsers that scroll to the top of the document whenever the page is refreshed.
The alternative is to split your window into two frames, a very small one that loads a page full of JavaScript functions with a META refresh, and your main frame with your content. The small frame simply updates the data in the larger frame whenever the refresh triggers. The downside here is you increase the complexity of your page, rewriting a page using JavaScript is difficult in older browsers, and as a bonus you get all the problems inherent with using frames. There *is* a way to keep a connection between a browser and HTTP server alive and send updates through that, but it's hairy, and I don't know how well it'd scale. Try searching the web for multipart/x-mixed-replace, if you're feeling brave. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 24, 2001 11:17 AM To: [EMAIL PROTECTED] Subject: Real time web page? Hi everyone. We are starting a new project and have a requirement for real-time updates in a web browser. Does anyone know of any tools that allow for this, apart from applets? Cheers, Dave
