This article demonstrates how to provide download of a file in ASP.net along with tracking its success and failure. It will be useful especially in e-commerce system that offers downloadable product option. In e-commerce system it is very important to keep track of status of download. For a download option there can be two scenarios 1.complete/success download and 2.failure download. In e-commerce system user may have a limited number of download allowed which is one in most of the cases. If a download is successful, it should update the record which will indicate the user that he has already downloaded the file or increment the download count by 1. But for failure download the user should be able to download it again or the download count should remain same. So this article will help in tracking such status of download. While working on a e-commerce project I had a requirement to implement such a functionality where the success/failure of the download can be tracked. After searching for the solution I found that there is no such article related to similar problem. Then I came up with this solution after reading an article on transferring file in small packets. I hope this solution will help others struggling with similar problem. Read more: Codeproject
