The online engines emulate a request as it would come from a web browser, which
is why the HTTP headers in the default settings should also be set the way a
standard web browser would set them.

The engine has been revised; there is now the option ``adobe_content_types``
with which it is possible to configure engines for video and audio from the
adobe stock. BTW this patch adds documentation to the engine.
To test all three engines in one use a search term like::
!asi !asv !asa sound
