Hello, i have developed a robot-application using the libwww. In a special Case i need to realize an automatic authentication within the robot-profile. (setting the user-id and the password without prompting the user...) But i still have no Luck ! (I think, i have to modify the "prompt_user"-Function in HTAABrow.c) Does anyone have any ideas ? Thanks. Martin (mostrowski @marlowe.iosys.de)
