Instead, custom error pages can be displayed. Custom error pages can be defined at 2 levels 1. Application Level - In the web.config file using "customErrors" element. 2. Page Level - In the Page directive, using "ErrorPage" attribute. Page level custom error pages takes precedence over application level custom error pages. Custom error pages provide the flexibility of displaying a specific page in response to one or more of the available HTTP status codes. To specify the custom error pages at an application level, use customErrors element in web.config The mode attribute determines when a custom error page is displayed over the yello screen of death, exception page. Mode attribute can have On, Off, or RemoteOnly. Default is RemoteOnly. On - Custom error pages are displayed both on local and remote machines Off - Custom error pages are not displayed anywhere RemoteOnly - Custom error pages are displayed on remote machines, and exception page on local machine If the redirection is done in Application_Error() event handler in Global.asax, custom error pages will have no effect. In your application, if you have to display specific custom error pages for specific http status codes, then use custom errors. If you just have one generic error page, then Global.asax can be used. Please note that, the exception object needs to be retrieved, before the user is redirected to a custom error page. Because a custom error page is displayed through redirection, the context for the error is lost and Server.GetLastError returns nothing from the target custom error page.

Part 70 Authorize and AllowAnonymous action filters in mvc

Part 70   Authorize and AllowAnonymous action filters in mvc

Link for code samples used in the demo http://csharp-video-tutorials.blogspot.com/2013/08/part-70-authorize-and-allowanonymous.html Link for csharp, asp.net, ado.net, dotnet basics, mvc and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists In this video, we will discuss Authorize and AllowAnonymous action filters in mvc. In ASP.NET MVC, by default, all the controller action methods are accessible to both anonymous and authenticated users. If you want action methods, to be available only for authenticated and authorised users, then use Authorize attribute. Let us understand "Authorize" and "AllowAnonymous" action filters with an example. 1. Create a blank asp.net mvc4 application. Name your application MVCDemo. 2. Right click on the "Controllers" folder and add HomeController. Copy and paste the following code. public class HomeController : Controller { public ActionResult NonSecureMethod() { return View(); } public ActionResult SecureMethod() { return View(); } } 3. Right click on NonSecureMethod() and add a view with name = NonSecureMethod. Similarly add a view with name = SecureMethod. 4. Associate MVCDemo project with IIS. a) Right click on the project name in "solution explorer" and select "Properties" b) Click on "Web" tab c) Select "Use Local IIS Web Server". In the "Project Url" textbox, type - http://localhost/MVCDemo d) Click "Create Virtual Directory" button 5. Open IIS. Expand "Sites" and then "Default Web Site" and select "MVCDemo". Double click on "Authentication" icon. Enable "Anonymous Authentication" and "Windows Authentication", if they are not already enabled. 6. At this point, you will be able to access, both "SecureMethod" and "NonSecureMethod", by visiting the following URLs. http://localhost/MVCDemo/Home/SecureMethod http://localhost/MVCDemo/Home/NonSecureMethod 7. If you want "SecureMethod" to be available only for authenticated users, then decorate it with "Authorize" attribute. [Authorize] public ActionResult SecureMethod() { return View(); } 8. Now, if you navigate to "http://localhost/MVCDemo/Home/SecureMethod", then you will be prompted for your windows credentials. If you don't provide valid windows credentials or if you click cancel, you will get an error - 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied. You should be able to access "NonSecureMethod" 9. Now remove the [Authorize] attribute from SecureMethod(), and apply it on the HomeController. [Authorize] public class HomeController : Controller { public ActionResult NonSecureMethod() { return View(); } public ActionResult SecureMethod() { return View(); } } At this point, "Authorize" attribute is applicable for all action methods in the HomeController. So, only authenticated users will be able to access SecureMethod() and NonSecureMethod(). 10. To allow anonymous access to NonSecureMethod(), apply [AllowAnonymous] attribute. AllowAnonymous attribute is used to skip authorization enforced by Authorize attribute. [AllowAnonymous] public ActionResult NonSecureMethod() { return View(); }
