Hi
     I am uploading a file to the server. If the file size is larger, it takes more time,Hence clients may thing some thing is wrong with the site. To over come this i need to display a progressbar with uploading status.

Thanks if any advice.....

The problem with that article is that it discusses a page that takes a long time to load. The problem the poster is posing is the case where the user is uploading a large file.

Unfortunately, there's not way to tell the browser about the status of such an action because of what's happening. When you upload a file thru a Http POST action, the browser's HTTP request contains the binary data for the file being uploaded. The server won't do anything with the file (or request for that matter) until the request has been completely received. I don't think there is any way around this problem.

mehdi,

Again, this is not what the poster is looking for. This is a "your request is being processed, please wait" indicator. Usually how this works is you draw a simple page with a graphic to indicate "progress" and then you use a meta tag to refresh to the page that is actually going to do the work. The second page requested is what takes time.

The OP is asking "how can I show the user the progress of their file upload?" In technical terms they are looking to provide the user feedback on the status of their browser posting the HTTP request to the server. During that process the server isn't even involved, apart from sitting there receiving the bytes of the request as it's uploaded. So the server can't tell the browser the status because it hasn't even started to generate a result because it's waiting for the incoming HTTP post request to finish coming in.

This could be done as a client side control that actaully uploads to a webservice, rather than using the standard posting method. Then the client side control can show progress- much like with Windows Update... Of course, if you want it to be cross-browser you need to go to Java.
