Add a Progress Indicator to your asp page

Sometimes when developing a web application, you need to query a large amount of data, manipulate it and present it in a beautiful and readable way. That kind of operations – given that you created a resource optimized sql query – might take time and the user, waiting for data to appear on the screen, might get nervous not knowing what is really happening to the submitted request. So what? There are risks involved in that waiting: the user might hit other buttons sending multiple requests to the server. Again the user might submit data update more than one time. Or, simply, the user might think that your application is lousy and really slow (while you know that the user just submitted a very complicated query and you can’t do much about it in terms of speeding up the process!).
