No idea.

But if he took the files from here then it will work. Locally and without detecting proxied connection (which needs a login).
--edit
after taking a look it is a different approach: he chose the solution with a python http server (which also came to my mind but with socat it is a one-liner and lightweight). Unfortunately this will also not be able to detect a login-needed connection.
Mine just returns success, so WLAN is kept open (even if we are behind a blocked/proxied connection and have no internet access)
His will return error if we are behind such 'proxy' and WLAN gets shut down.
BUT the python http server solution is extendable and could be modified so a 200 (OK) or 300 (various?) could be interpreted correctly. Therefore we would need to know what is done in icd2 after receiving http response of 200/300!

btw: maemo.org techstaff is checking for a possibility to host such www service
