Tukukkk

So, I'm using some cookies in my project. I can see my three cookies in my browser and their values.

The problem is when I try to get the value of one of them something strange happens:

If the value is, for example, "1" I can get the value of the cookie. But, if the value length is higher than 1 I get null...

Picture of the cookie with value "1" -> Picture with the cookie value

Picture of the cookie with value "11" -> Picture with the cookie getting null value

Here's is how I get my cookie:

HttpCookie authenticationCookie = HttpContext.Current.Request.Cookies["Test"];

Can someone help me?

EDIT

Here is how i set my cookie:

FormsAuthentication.Initialize();

        var authenticationTicket =

            new FormsAuthenticationTicket(1,

                                          user.Name,

                                          DateTime.Now,

                                          DateTime.Now.Add(FormsAuthentication.Timeout),

                                          false,

                                          _cookieManager.SerializeUserData(user),

                                          FormsAuthentication.FormsCookiePath);



        HttpContext.Current.Response.Cookies.Add(

            new HttpCookie(

                FormsAuthentication.FormsCookieName,

                StringHelper.Compress(FormsAuthentication.Encrypt(authenticationTicket))));
