Hi aznan,
If you want to use true policies you need to deploy a hotfix available thru
Microsoft in the following article:
WinINet ignores the policies that you set when you create a custom
administrative template file in Windows XP with Service Pack 2 at
http://support.microsoft.com/default.aspx?scid=kb;en-us;904710
This is an administrative template to do what you need.
;-----------------Begin Code---------------
CLASS USER
CATEGORY !!Internet
CATEGORY !!ProxySettings
POLICY "Use HTTP 1.1"
KEYNAME "Software\Policies\Microsoft\Windows\CurrentVersion\Internet
Settings"
VALUENAME EnableHttp1_1
VALUEON NUMERIC 1
VALUEOFF NUMERIC 0
END POLICY
POLICY "Use HTTP 1.1 Through Proxy Connections"
KEYNAME "Software\Policies\Microsoft\Windows\CurrentVersion\Internet
Settings"
VALUENAME ProxyHttp1.1
VALUEON NUMERIC 1
VALUEOFF NUMERIC 0
END POLICY
END CATEGORY
END CATEGORY
[strings]
Internet="Internet Explorer Advanced Settings"
ProxySettings="HTTP 1.1 Settings"
;----------------End Code------------------
If you do not want to use True policies just replace the "keyname" with the
one on Mark Heitbrink post.
