Loggin in as a different user

Hello ,

I want a link that the users can click which supports logging in as a different user and then redirects them back to the same page.The issue is the page currently the user is on is also a layouts page .So the below code will work but take the user to the home page not the layouts page they are currently on which is

http://test.net/_layouts/15/EditProfile.aspx

function ChangeLogin()
{
    var url = window.location.host;
    alert(url);
    var loginurl ="http://" + url + '/_layouts/closeConnection.aspx?loginasanotheruser=true'
   
      location.href = loginurl;

}

Thanks
