Culture is lost when redirect to login

[LazZiya]

If unlogged user clicked on a page that requires authorization, the user is redirected to login page but with the culture parameter is lost!

e.g. : unlogged user clicks on below link:
http://localhost:1234/tr/Identity/Account/ChangePassword/
he will be redirected to :
http://localhost:1234/Identity/Account/Login/

add login redirection rules in startup:

services.ConfigureApplicationCookie(options =>
{
    options.Events = new CookieAuthenticationEvents
    {
        OnRedirectToLogin = ctx =>
        {
            var requestPath = ctx.Request.Path;
            var culture = ctx.Request.RouteValues["culture"];
            ctx.Response.Redirect($"/{culture}/Identity/Account/Login/?ReturnUrl={requestPath}{ctx.Request.QueryString}");
            return Task.CompletedTask;
        }
    };
});

improved approach provided in commit c1f7e3d

services.ConfigureApplicationCookie(options =>
{
    options.Events = new CookieAuthenticationEvents
    {
        OnRedirectToLogin = ctx =>
        {
            var culture = ctx.Request.RouteValues["culture"];
            var requestPath = ctx.Request.Path;

            if (culture == null)
            {
                culture = "en";
                requestPath = $"/{culture}{requestPath}";
            }

            ctx.Response.Redirect($"/{culture}/Identity/Account/Login/?ReturnUrl={requestPath}{ctx.Request.QueryString}");
            return Task.CompletedTask;
        }
    };

});
