Inet Control and Dial-Up Management

Question 1:

How can I avoid the Inet control to execute a URL without reading the file from the cache?

Question 2:

I have a timer triggered Inet control. I want it to be activated whenever the Dial-Up connection is cut off. Inet responds to the connection breakdown however sometimes it retrieves data from the cache instead of URL this, in a way, fakes Inet that icResponseCompleted=True, whereas in fact it is not or should not be. So how can I reliable detect dial-up connection breakdowns and reestablish connection?
