Throw new ArgumentNullException("context") Public string GetRequestCookie(IOwinContext context, string key) Then, you need to replace the default cookie manager with the following implementation: public class SystemWebCookieManager : ICookieManager HttpContext.SetSessionStateBehavior(SessionStateBehavior.Required) Īpp.UseStageMarker(PipelineStage.MapHandler)
Var httpContext = context.Get(typeof(HttpContextBase).FullName)
FACEBOOK SESSION EXPIRED TWITTER CODE
To be able to use session in OWIN, the following code should be placed in Startup.cs before any middleware is registered. The preferred solution to this problem would be using a different way to store session-related data, or replace the default ChunkingCookieManager class by another implementation which will use HttpContext to interact with cookies. When a postback occurs, DotVVM will throw the following exception: : SessionID cookie is missing, so can't verify CSRF token If ASP.NET session is used at that request, or collection is changed, the changes to the cookie made by DotVVM are overwritten by the HttpContext and the CSRF token will be lost. When the browser makes the first request to a DotVVM web application, it stores the CSRF token in the cookie. When the application interact with cookies using through (the classic ASP.NET way), there is a conflict and the changes made by the ChunkingCookieManager will be lost.ĭotVVM needs to store CSRF token in a cookie to provide a secure way of executing postbacks. By default, the ChunkingCookieManager class is used. OWIN offers its own extensible way of working with cookies. We recommend to avoid using session completely as it causes a wide variety of problems, especially when the user has multiple tabs or browser windows open. It is relevant for you only if the application needs to interact with ASP.NET Session, or with cookies using. This topic is related to the OWIN version of DotVVM only.
