asp.net mvc - The "Back" button and the anti-forgery token -

i'm getting runtime error related the anti-forgery attribute.

perform next steps:

create mvc web application , start register joe@acme.org sign out register jane@acme.org sign out login joe@acme.org hit button login jane@acme.org

error: the provided anti-forgery token meant different claims-based user current user.

what can done prevent error occurring?

this 1 way of ignoring error , returning user login screen. it's example.

create new class called handleantiforgerytokenerrorattribute inherits handleerrorattribute. override onexception method.

public class handleantiforgerytokenerrorattribute : handleerrorattribute { public override void onexception(exceptioncontext filtercontext) { filtercontext.exceptionhandled = true; filtercontext.result = new redirecttorouteresult( new routevaluedictionary(new { action = "login", controller = "account" })); } }

go filterconfig class , register attribute global filter.

public class filterconfig { public static void registerglobalfilters(globalfiltercollection filters) { filters.add(new handleerrorattribute()); filters.add(new handleantiforgerytokenerrorattribute() { exceptiontype = typeof(httpantiforgeryexception) } ); } }
