* Positive test for handling exceptions thrown by an included servlet.
* Request parameter <strong>exception</strong> is used to indicate the type
* of exception that should be thrown, which must be one of
* <code>IOException</code>, <code>ServletException</code>, or
* <code>ServletException</code>. According to the spec, any exceptions of
* these types should be propogated back to the caller unchanged.
