Login page first before being able to download a file
<p>I am new to ASP.NET and web application developing.  What I'm trying to implement is, I am storing a file on the web server and is supposed to give the link of the file to the user for them to download the file.  The link and the "downloading" process is easy but I wanted to make it more secure like having the link go through the login page, then the user will enter his/her credentials, if success, then the file will be automatically downloaded.</p>

<p>Does anyone know how where should I start or what is the name of this kind of method/processing for me to be able to start my research.</p>

<p>Thanks.</p>
