---------------------------+------------------------------------------------
 Whenever a server error prevents the AJAX viewer from updating, there is
 no feedback indicating that a problem occurred. The map just stops
 working. This can be really confusing.

 Most significantly, whenever a session expires, the viewer should report
 that fact to the user.

 Also, the viewer API should have a hook for error handling, including the
 ability to override the default error handler. One example use for this
 feature might be some custom code for "rebooting" a session, or better
 display of error message.

 This problem may extend to the DWF viewer as well.
