Altough I can easily connect to the site and login, I cannot spot out how to go further because I loose myself into javascript and frame problems.
Now I was thinking, perhaps there is a way to
bring Win32::IEAutomation to connect to an existing IE session (I know that this can be done for Excel instances for example).
In this way I could move to the desired page by hand but then navigate further and fill forms automatically through Win32::IEAutomation
