User click on the button on the webpage to download the file, i want to track the file is being downloaded to the user machine or not using client side code like javascript/JQuery.
On button click, ASP.NET .ASHX Web handler code is called which return the file to be downloaded.
Also can we check using javascript/JQuery whether the user is having issue (security, firewall etc.) in downloading the file, when user click on the download button on the webpage.
