Logging in as a different user in sharepoint 2013 - sharepoint

Question

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

Answer 1

Method 1:
This can be done if you have access to the 2013 server 15 hive. Open 15 hive --> Control Templates-->welcome.ascx . Add the below xml entry:
<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser"
Text="<%$Resources:wss,personalactions_loginasdifferentuser%>"
Description="<%$Resources:wss,personalactions_loginasdifferentuserdescription%>"
MenuGroupId="100"
Sequence="100"
UseShortId="true"
/>
Note: This is a farm level change and will affect all web application and sites on that server.
Method 2:
In the page where you want to add the link to add below tag:
Sign in as diff user
LoginAsAnother() is the method used by SharePoint internally in the method 1(ie OOTB menu under logged in user name).
Here provide the server relative web url before '/_layouts/15/closeConnection.aspx'.
