why other web project show me logged in?
<p>I'm working on two separated web projects, but use same authentication scenario for both of them. 
Here is a part of my login code:</p>

<pre><code>public void Login(string username, string password, bool staySignedIn)
{
    if (this.IsLockedOut(username))
    {
        this._view.ShowMessage("Your account has been locked!");
        return;
    }
    else if (!this.IsApproved(username))
    {
        if (!string.IsNullOrEmpty(this.webContext.CurrentUserID))
        {
            this.membershipService.ChangeApprove(this.webContext.CurrentUserIdFromQuery);
            this.DoLogin(username, password, staySignedIn);
        }
        else
            this._view.ShowMessage("Your account is not activated yet");
    }
    else
        this.DoLogin(username, password, staySignedIn);
}

private void DoLogin(string username, string password, bool staySignedIn)
{
    try
    {
        FormsAuthentication.SetAuthCookie(username, staySignedIn);
        if (!string.IsNullOrEmpty(this.webContext.GetReturnUrl))
            this.redirector.GotoUrl(this.webContext.GetReturnUrl);
        else this.redirector.GotoProfileDefault();
    }
    catch (Exception ex)
    {
        this.logger.PrintToLogFile(ex, false);
        this._view.ShowMessage("Some error code");
    }
}
</code></pre>
