IE 8 sharing session among different Explorer Window for same domain.
Like if you are a logined at hotmail.com in IE 8, and you have open another explo
Your question isn't that clear.
Are saying in IE8 when you open a new window that window shares the same session as the previous window hence any login made in one is shared by the other?
If so then that would be normal behaviour and not any different to the way IE7 handled it.
OTH are you saying that when you open a new window in IE8 it doesn't continue to share the same session as the previous window? If you mean using the New Window action from the Page menu then that would appear to be a bug to me but it doesn't happen on my copy of IE8.
If by new window you mean starting a new instance of IE from quick links or Start menu then it would be correct for that to start a new session and not share session cookies with the other session you have running.
I suspect this last is the real situation, previously the standard IE link added to Start Menu or Desktop would simply open a new window using one of any existing IE sessions currently running, IE8 doesn't do that it will invoke a new session from this link.
Modify IE8 Shortcut to Permanently Launch New IE Browser Window in New Session
Right click on the IE8 shortcut (all IE8 shortcuts or icons on desktop, Start Menu, Quick Launch bar or Taskbar that you want it to run as a new instance session have to be changed), and choose Properties from the right click context menu. Then, append -nomerge to the end of the of the program path in “Target” text box at “Shortcut” tab. For example,
“C:\Program Files\Internet Explorer\iexplore.exe” -nomerge

Any new window that you open (using iexplore.exe and not openning from inside another window) shares the same session as any previous.

Don't tell me that this is not a bug. This is a huge one! (maybe a design bug)
Most users do not expect this behavior and complain that there is a "problem with our site" because they have another window open on some radiostation which makes sure the session of another site is persisted, I then have to explain to them that Microsoft/Google decided that that's the "right" way. The default should be -nomerge and not the other way around.
I prefer using "Run" and just type "iexplore.exe -nomerge"
Create a new shortcut to ieplore.exe, add the -nomerge switch. This will always start a new session.
You can prevent new windows from sharing session cookies by File -> New Session, however you cannot prevent new tabs from sharing data by default.
