asp.net mvc - How Request.IsAuthenticated work in mvc4 exactly -

i made 2 mvc project use login form before start use code login

 public actionresult login(accountlog usr)     {         accountlog personindatabase = db.accountlogs.firstordefault(m => m.usercode == usr.usercode);                  formsauthentication.setauthcookie(personindatabase.username, true);                 viewbag.id = personindatabase.usersid;                 return redirecttoaction("main", "main");} 

when run program @ check first if(request.isauthenticated) if true return view if else redirect login page

 public actionresult main()     {         if (request.isauthenticated)         {             return view();         }          return redirecttoaction("login", "account");      } 

it worked fine noticed if run first program , made success login , close not made logout , run second program not logged yet open logged person mean if made login first 1 , open second open fine , vise versa how can differentiate between 2 project login how can made alternative request.isauthenticated if thing in question don't clear leave comment clear able me

from described trying login same application using same browser session in 2 different tabs without logging out first user.

when login success authentication cookie set in browser. cookie sent server each time server can validate user.

as trying login ( or expect login) second tab using account, see first user logged in authentication cookie account still persisted in browser. authentication cookie expire when user logs off.

so can either.

1. test 2 accounts using 2 different browsers(e.g. chrome , firefox)
2. log off first account before trying login using account in same browser.

hope helps!
