ASP.NET Suppress Forms Authentication Redirect

Module that prevents ASP.NET Forms Authentication to redirect the user to the login page. This is helpful for AJAX, JSON, and all other of non Web Representation (Views/Pages) type of requests.

For more information read Phill Haack's post about this http://haacked.com/archive/2011/10/04/prevent-forms-authentication-login-page-redirect-when-you-donrsquot-want.aspx

Installation

Pull it from the online NuGet source, as easy as...

install-package aspnet.suppressformsredirect

Usage

You can use it from anywhere on your App, where you want to send a 401. We provide two approaches using HttpContext Items

HttpContext.Current.Items.Add(SuppressFormsAuthenticationRedirectModule.SuppressFormsAuthenticationKey, "true");

Or you are using WCF Web API (or something like MVC with more control on the Response) just include a custom header

var response = new HttpResponseMessage(System.Net.HttpStatusCode.Unauthorized);
response.Headers.Add(SuppressFormsAuthenticationRedirectModule.SuppressFormsHeaderName, "true");

throw new HttpResponseException(response);
