New session created after RedirectToAction in Asp.net MVC

Question

In an Asp.net MVC sometimes the session is lost after RedirectToAction to an another controller. I have build in global exception logging in Global.asax in Application_Error but nothing is logged at the moment when session is lost.

The problem happens a few times a day. Can you point me how to proceed to capture the reason of this problem?

Hi @Wojciech Rajchel

First of all, the first point: since there is no cookie, then we write a cookie.

HttpCookie aCookie = new HttpCookie("cookie1"); 
aCookie.Value = "";
aCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(aCookie);

Next, if you want all pages below your site to access this cookie. This is called the scope of the cookie, and you can set it like this:

HttpCookie aCookie = new HttpCookie("cookie1"); 
aCookie .Value = "written " + DateTime.Now.ToString(); 
aCookie .Expires = DateTime.Now.AddDays(1); 
aCookie .Path = "/";
Response.Cookies.Add(aCookie );

Best Regards
