I could implement an exception, but first I'd like to know if I can
capture the url of the attempted connection and force it to use
another? I'm wondering if imdb has another url for this service, and
if one does not return response I would like to attempt the same
search on the other server. Otherwise I'll have to report the service
is unavailable, which is fine as I can have the search held until
service resumes. Though I would much rather have the result now. ;)
also 'if movie.has_key('cover url')' was just a junk test. ;)
Thanks for your help Davide, I agree it is being a bit picky and the
application does not have to be 100% responsive, but it is nice to
cover all angles.
