ASIHttprequest Muliple request with one progressview

Question

After the purchase is completed ,i want to donwload image, audio and video from server.

Currently i am able to download the image and can see the progress in UIProgressView but i am not sure how can we show the single UIProgressView for multiple url requests.

I would like to know whether we can show one UIProgressView for multiple url request using ASIHttpRequest.

please let me know how to proceed? and thanks a lot
