The point about the handler, created from the Generic Handler option with its.
For the sake of simplicity, the default value of false can be left as it is. The first houses the logic that needs to be run to process the current request, and the second dictates whether the handler can be pooled and reused for other requests. The Handler contains two methods - ProcessRequest and IsReusable. Public void ProcessRequest( HttpContext context)Ĭ = "text/plain"

Users who successfully authenticate will be directed to Default.aspx, which contains links to downloadable files: If( FormsAuthentication.Authenticate(username, password))įormsAuthentication.RedirectFromLoginPage(username, false) Login.aspx contains a straightforward Login Control: Īnd the code-behind contains the authentication logic: protected void Login1_Authenticate( object sender, AuthenticateEventArgs e) aspx files are mapped to aspnet.dll, Forms Authentication kicks in and users who have not already logged in will be redirected to Private/Login.aspx. Since that has been protected under Forms Authentication, and since all. Any requests for that URL will invoke the default document, which in this case is Private/Default.aspx.

Forms Authentication in ASP.NET only works with requests that are handled by ASP.NET in IIS 6.0 (typically Windows Server 2003), which means that non-ASP.NET content bypasses aspnet.dll, and is not subject to it.
