This event is fired every time the wodHttpDLX control
changes the current operation that it is performing. Even
though most of these operations also result in firing other
events, the user can monitor this event to see the reason
for an operation's completing unsuccessfully, or can
ignore other events and take appropriate action depending
on the wodHttpDLX.State value. Refer also to the here
for a list of possible states.
If AutoRedirect
property is set to True, it is possible that
wodHttpDLX sends more than one request based on your URL.
This depends purely on server's responses. In such
cases, state changes may vary and may look as 'out of
sequence'.
