All other browsers (FireFox, Chrome, etc.) cookies persist ok.
NOTE: Using IE8 to browse to my web app by using the web app’s IP address instead of URL will persist cookies ok.
My IE8 browser options are set to Accept All Cookies.
This fails on IE8 on more than one computer.
I can see in IE8 > Dev Tools > Cache > View Cookie Info that the cookies are not getting stored.
SOLUTION: The problem went away after I redid my methods for storing cookies…
