Shashi, have you considered using forms authentication to authenticate your users?

The user is authenticated before your site code is executed. ASP.NET checks if the user is permitted to use the resource before your code is executed...so that means that if the user logs in and is not allowed to use a resource...but they type the URL to the resource ASP.NET will redirect them to an error page stating that they aren't allowed access to the page/picture/resource that they are trying to access.

Yes I am using forms authentication to authenticate user and location path attribute is set to a SecureFolder where login welcome ,test and result pages are stored and in which also all the .mht files are stored.
please it's urgent..

Shashi, in the "secure" page you can use this kind of code so that user authentication can be checked.

protected void Page_Load(object sender, EventArgs e)
    {
        if (User.Identity.IsAuthenticated == false)
        {
            Server.Transfer("../Login.aspx");
        }
        if (Roles.IsUserInRole("Administrator") == false)
        {
            Server.Transfer("../unauthorized.aspx");
        }
    }

Ok I think that you just need to add an additional secure folder...(I could be wrong here because I don't have a very good idea about what your system's doing)


So you'll have publicly available content (like the Login page and maybe a Sign Up page).

Then you'll have a folder that contains the restricted content that users aren't allowed to access...

Then you'll have a folder containing the .mht files which is also restricted.

Each folder should have a web.config file in it where you can specify which users are allowed access to the information and deny anyone else.

Thanx a lot for your reply , but i am facing a problem not by web.config location path element , actually problem is that when forms authentication authenticates a user then they are allowed to acess all the folder and i am not able to restrict them and it's true that files should be accessed by user by giving their same credential as he is given in the login page, but i only want to restrict them to access these (*.mht) files only on my Test Page not on my Welcome Page or any other page redirects after login page....... looking for your reply...

[shashi shekhar singh]

Respected Sir,

I think in web.config by using <Httpmodules><H ttpmodules> and <httphandlers > <httphandlers > , i can restrict the file access from other pages, if you think so then please give me an idea how to do this actually this is really new for me ....

thanx a lot ..
