AJAX进度栏-轮询,彗星?

I would like some advice on how to implement the following:

I would like to make my users aware of the progress of a task that is running on my server via AJAX. My server runs a PHP script that downloads a file via shell command using the popen function. It periodically echos/prints what is happening. I would like to capture this output using AJAX and present it to the user.

I was told in another question that I might need to make use of polling or comet? I would really appreciate any help or guidance on how to achieve this in the simplest and most efficient way. Hopefully, I can still make use of JQuery.

Thank you all for taking the time to read this.

P.S. I was able to get this far with thanks to the stackoverflow community. :)

    This sounds like a great opportunity for Ajax long polling, which is one of the myriad techniques used in general Comet implementations. There's another question on Stack Overflow with sample code.
