FND:How to create a link in IE favorite to directly login into apps

I'm lazy to type username and password whenever I open my testing 11i system. So I simply check the html source of the login page and get the submit detail of the login button, then following url can bring me directly to responsibility page. instance name is TEST

http://host:port/pls/TEST/OracleMyPage.Home?i_1=user_name&i_2=password&rmode=2&c_sec_grp_id=

That's all . Then I don't have to login and can directly enter responsibility screen.

Furthermore, we can even directly open the form by such approach, for example, I need to open System Admin responsibility directly from IE favorite, then we can open the html source of the responsibility page and check the actual url , eg,

http://host:port/pls/TEST/fnd_icx_launch.runforms?ICX_TICKET=&RESP_APP=SYSADMIN&RESP_KEY=SYSTEM_ADMINISTRATOR&SECGRP_KEY=STANDARD
