    -- To use a SOCKS4 or SOCKS5 proxy, simply set the following
    -- properties prior to communicating with the HTTP server:
    -- The SOCKS hostname may be a domain name or 
    -- IP address:
    EXEC sp_OASetProperty @http, 'SocksHostname', 'www.mysocksproxyserver.com'
    EXEC sp_OASetProperty @http, 'SocksPort', 1080
    EXEC sp_OASetProperty @http, 'SocksUsername', 'myProxyLogin'
    EXEC sp_OASetProperty @http, 'SocksPassword', 'myProxyPassword'
    -- Set the SOCKS version to 4 or 5 based on the version
    -- of the SOCKS proxy server:
    EXEC sp_OASetProperty @http, 'SocksVersion', 5
    -- Note: SOCKS4 servers only support usernames without passwords.
    -- SOCKS5 servers support full login/password authentication.
