Computer Configuration\Administrative Templates\Windows Components\Internet Explorer\Security Features\AJAX User Configuration\Administrative Templates\Windows Components\Internet Explorer\Security Features\AJAX Description
The WebSocket object allows websites to request data across domains from your browser by using the WebSocket protocol. This policy setting allows administrators to enable or disable the WebSocket object. This policy setting does not prevent client-side communication across domains via other features in Internet Explorer 10. Also, this policy setting does not prevent a site from requesting cross-domain data through a server. If you enable this policy setting, websites cannot request data across domains by using the WebSocket object. If you disable or do not configure this policy setting, websites can request data across domains by using the WebSocket object. By default, the WebSocket object is enabled.
Registry
Software\Policies\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_WEBSOCKET Software\Policies\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_WEBSOCKET Value name: iexplore.exe
Enabled: iexplore.exe = 0
Disabled: iexplore.exe = 1
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
