Are posible login to ITSmobile via URL

In SAP WEB console we use login via URL f.e. to login in client 001 and server servA.dom1.dom2 with username user1 and password pass12345 we use next URL

http://servA.dom1.dom2/?p=mc3090audio&c=001&u=user1&s=pass12345&a

now we try go to ITSmobile and for sapserver sapserv1

http://sapserv.dom1.dom2:8000/sap/bc/gui/sap/its/test/mobile/testservice?sap-client=001&&sap-language=EN&sap-login=user1&sap-password=pass12345

but it not work propertly. Instead open generated form for first screen are opened logon window. Why logon wia URL doesn`t work?
