You install hotfix 904710 for Windows XP Service Pack 2 or Windows XP Service Pack 3. When you use Internet Explorer to connect to a Web site, the trace analysis of the connection may indicate that Internet Explorer is sending HTTP/1.0 GET requests instead of sending HTTP/1.1 GET requests.
This problem occurs even when you enable the Use HTTP 1.1 option and the Use HTTP 1.1 through proxy connections option in Internet Explorer.

(http://support.microsoft.com/kb/904710/ )WinINet ignores the policies that you set when you create a custom administrative template file in Windows XP with Service Pack 2
This problem occurs because of a design change in how the Wininet.dll file reads the values of the Use HTTP 1.1 option and the Use HTTP 1.1 through proxy connections option as a policy. In this case, the Security_HKLM_Only registry entry is enabled. This design change does not consider the effect of the Security_HKLM_Only registry entry. When the Security_HKLM_Only registry entry is enabled, the default settings for the Use HTTP 1.1 option and for the Use HTTP 1.1 through proxy connections option are set to be disabled. By default, the EnableHttp1_1 registry entry and the ProxyHttp1.1 registry entry do not exist. Therefore, when the Wininet.dll file tries to read them in the registry, the values of these registry entries are determined to be turned off.
The Security_HKLM_Only registry entry is stored in the following registry subkey:

HKEY_LOCAL_MACHINEregistry subkey. To do this, follow these steps:
