progress

Hey Guys, I want to create a section in my site, where a user has a few simple update buttons.

Each of these update buttons will be going to the server, and will do a long crunching behind the scene.

While the server crunches data, I want the user to have a some kind of progress indicator, like progress bar or textual percentage.

I'm using jQuery as my javascript library, and CodeIgniter (PHP) as the server-side framework, if it's important...

What I was thinking about is using PHP's flush() function to report progress status to jQuery, but I'm not sure that jQuery's ajax functions are reading the output before it's complete...

So any advice/explanation would be useful and helpful!

Thanks :)
