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.

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_MACHINE\Software\Policies\Microsoft\Windows\CurrentVersion\Internet
Settings
This behavior change started with the hotfix that is included in Microsoft Knowledge Base article 904710. The behavior was implemented in the following version of Wininet.dll:

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To work around this problem, manually add the EnableHttp1_1
registry entry and the ProxyHttp1.1 registry entry to the
HKEY_LOCAL_MACHINE
registry subkey. To do
this, follow these steps:
- Click Start, click Run,
type regedit, and then click
OK.
- Locate and then click the following registry
subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet
Settings
- On the Edit menu, point to
New, and then click DWORD Value.
- Type EnableHTTP1_1, and then press
ENTER.
- Right-click EnableHTTP1_1, and then click
Modify.
- Type 1, and then click
OK.
- On the Edit menu, point to
New, and then click DWORD Value.
- Type ProxyHttp1.1, and then press
ENTER.
- Right-click ProxyHttp1.1, and then click
Modify.
- Type 1, and then click
OK.
- Exit Registry Editor.
Note By default, the two registry entries will be added.
