 <meta http-equiv="refresh" content="@FormsAuthentication.Timeout.TotalSeconds;url=@FormsAuthentication.LoginUrl" />

If you are making a site like facebook, then using the above method would cause number of users to decrease from 1 billion to 0. Why? because this method counts only full page refreshes, not ajax requests.

So, next method is using Javascript and thanks to this blog. automatic-redirect-upon-session-timeout-using-javascript/

Following is the same logic with MVC Forms authentication specific Razor code.

First, the web.config Forms Auth entries.

<system.web>    <authentication mode="Forms">       <forms loginUrl="~/Login" slidingExpiration="true" timeout="20" /> …
