Error Messages (winhttp.h)

The server requires SSL client Authentication. The application retrieves the list of certificate issuers by calling [**WinHttpQueryOption**](/windows/desktop/api/Winhttp/nf-winhttp-winhttpqueryoption) with the **WINHTTP_OPTION_CLIENT_CERT_ISSUER_LIST** option. For more information, see the **WINHTTP_OPTION_CLIENT_CERT_ISSUER_LIST** option. If the server requests the client certificate, but does not require it, the application can alternately call [**WinHttpSetOption**](/windows/desktop/api/Winhttp/nf-winhttp-winhttpsetoption) with the **WINHTTP_OPTION_CLIENT_CERT_CONTEXT** option. In this case, the application specifies the WINHTTP_NO_CLIENT_CERT_CONTEXT macro in the *lpBuffer* parameter of **WinHttpSetOption**. For more information, see the **WINHTTP_OPTION_CLIENT_CERT_CONTEXT** option. **Windows Server 2003 with SP1 and Windows XP with SP2:** This error is not supported.
