facebookexternalhit should be added to robots.cfg. Here is Facebook's
explanation of how it's used:
"Facebook allows its users to send links to interesting web content to
other Facebook users. Part of how this works on the Facebook system
involves the temporary display of certain images or details related to
the web content, such as the title of the webpage or the embed tag of
a video. Our system retrieves this information only after a user
provides us with a link. You may have found this page because a
Facebook user sent a link from your website to other Facebook users.
If you have any questions or concerns about any links or content sent
by one of our users, please contact us at legal at facebook.com."
Facebook itself retrieves the external page or image with the
facebookexternalhit UA so that UA shouldn't be given a session.
Should I submit a bug for this?
