When
set to True, WebArchiveX considers URLs to directories as
markups. For example, URL http://www.microsoft.com/
points to the root directory of www.microsoft.com website, the actual URL being
retrieved is something like http://www.microsoft.com/default.aspx
and the output is a regular HTML. This ensures that WebArchiveX will
archive this type of content with a correct MIME type and will handle it
correctly if the parameters require additional parsing or spidering.
