I have a webserver from where users can download files that are specific for each user. To be sure each user can only download its own files they must authenticate via

Answer 1

Set the following in your Web.config

Place the following event in your Global.asax file.

protected void Application_BeginRequest(Object sender, EventArgs e)
{
}

Now whenever you type the URl like below.

http://localhost/dir1/jack.txt

The control will always move to Application_BeginRequest event. You have Request.Url information and Current User information and you can do the validation here.

Using below code

throw new HttpException(403,"Acess Denied");

or send the user to some another page with some user friendly message.
