After upgrading from ASP. 3.5 to Asp.net4, there are three types of cookies that cannot be saved after logging in (all normal before the upgrade):

1. Swim 3 in Speed mode (default mode).

2. UserAgent has been modified in Firefox.

3. Nokia phone comes with a browser or UCWeb browser to visit the blog Park Mobile version (m.cnblogs.com).

Today finally the culprit to find out, it is Request.Browser.Cookies.

If you use form validation in your program and use a cookie to save the user's login status, keep in mind that you should add cookieless= to <authentication mode= "Forms" >/<forms> " UseCookies ". If this is not set, cookieless will use the default value of UseDeviceProfile. With the UseDeviceProfile, the tragedy happened, ASP. NET will determine whether the current browser supports cookies based on Request.Browser.Cookies
