automatically updating?

[kjavia795]

I need a page to be automatically updating so that when a specific even occurs, it will display something. I know AJAX can do it, but in order to use it, it would be checking the database every few seconds to see if it was true, which is too much pressure on the server.... is there any other way to do this without putting stress on the database every 3 seconds?

You could try cron jobs, though I think the cpu usage would be the same.

I'll clarify here. the user wants data to be "pushed" to the user. As the user said: long polling isn't really an option.

I think Cron Jobs are your only option... the other option is to have a timer on Javascript and have it run every few seconds to check.

If anyone knows of any way to do it, suggest away!

Exactly! These are the only two options, and both hog resources.

What kind of 'event' is it?
If it's a new content page, what about using RSS and/or a page that displays a ummary of all new content - similar to how blogs work?
