    --  The SOCKS hostname may be a domain name or
    --  IP address:
    EXEC sp_OASetProperty @http, 'SocksHostname', 'www.mysocksproxyserver.com'

    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.
