Comment(by davidsarah):

 For anyone trying to test option C, the syntax above was wrong; it should

 However, I'm not sure that options B or C work for what we are trying to
 do. The problem we're trying to solve is that following a link from the
 contents of a Tahoe file may reveal the file's URL ('capURL'). Options B
 and C prevent the page at 'capURL' from seeing the referring URL (of the
 page containing the JavaScript), but they don't prevent leakage of
 'capURL' to a site that the page at 'capURL' links to.

 Only option A allows to you prevent sending a Referer header when
 following a link from a page with arbitrary contents (by serving that page
 via FTP).
