Override Automatic Cookie Handling

Due to the Royal Mail postal strike my company needed to use a new website for mail deliverys UKMAIL.BIZ

However this shoddy website had some nasty pre-reqs.

It had to be a trusted site, which was easy enough as this is managed via GPO.
It also required the "Override of automatic cookie handling" for first-party and third party cookies and "Always allow session cookies" to be enabled.

These are set in Internet options , under the privacy tab and advanced button. Now for obvious lock down reasons users cannot get into these settings and so i was looking for a Registry key to control this value for my users.

Unfortunately these values are set in a REG BINARY Value inside
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections
Other advanced IE setting are controlled in here so forcing the whole value was not
a nice option, plus i was unsure which of the binary values controlled the tick options
in here.

To workaround this problem i enabled the Internet options for the user by
setting the registry keys listed below, then talked the user through ticking the
correct boxes through the GUI. Then i removed the users access by putting the keys below
back to 1 values. The Defaultconnectionsettings key was then stored back with the
correct values to the users profile. (hybrid in my case)

HKCU\Software\Policies\Microsoft\Internet Explorer\Restrictions
noBrowserOptions to 0
HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel
Advanced = 0
Advanced Tab = 0
Security Tab = 0
