 # Using a proxy with Delivery Optimization
 
-**Applies to:**
-
-- Windows 11
-- Windows 10
-
 When Delivery Optimization downloads content from HTTP sources, it uses the automatic proxy discovery capability of WinHttp to streamline and maximize the support for complex proxy configurations as it makes range requests from the content server. It does this by setting the **WINHTTP_ACCESS_TYPE_AUTOMATIC_PROXY** flag in all HTTP calls.
 
 Delivery Optimization provides a token to WinHttp that corresponds to the user that is signed in currently. In turn, WinHttp automatically authenticates the user against the proxy server set either in Internet Explorer or in the **Proxy Settings** menu in Windows.
