Start multiple instance of Internet Explorer with separate sessions vs. Private Mode

IE instance with multiple sessions

For developers who work daily with IE, we all know the pain of close all Internet Explore instance and open a new window to have a fresh new session with clean data.

It is because of the default behavior in IE is using merged session.
No more pain my friends. This parameter come to rescue: –nomerge

So if you start your Internet Explore like this, you will be able to test various sessions.

What happen behind the scene:

 

For faster access, I edit the shortcut for Internet Explorer to be like:"C:\Program Files (x86)\Internet Explorer\iexplore.exe" –nomerge

Happy testing & debugging !
