Description
NSIA keeps logging exceptions when connections to the web-client are closed.
See below for two examples of the exceptions thrown:

This turns out to be more difficult than expected. The problem is that the individual views (those sub-classing View) throw ViewFailedExceptions for IOExceptions. They really ought to ignore these since these are dependent on the network connection. For example, IE will shut down the connection due to an unexpected mimetype.
