I have seen that the video lectures are hosted in a different URL
<http://mfile.akamai.com> instead of <http://ocw.mit.edu> .
How can I be sure that <http://mfile.akamai.com> is the only other URL in which
files of <http://ocw.mit.edu> are hosted ? Is there a way to check the already
downloaded site <http://ocw.mit.edu> to get a list of external links that
I can ceck if i have to download them also?
Help please
