[Bug 25818] [imports]: The dedup behavior with redirects should be clarified.

Thanks for the feedback, Anne. I wasn't aware of HSTS issue.

At the same time I realized some shortcomings of response URL approach:

 * It means UA have to request fetching for each <link> element regardless
there is (already) duped links, that makes de-dup no longer completely free. It
could be cached but 
   * UA needs some kind of interaction to fetch layer at least. 
   * As import loading could be highly concurrent, same URL can be requested in
parallel because we cannot see if these two results same URL. Also, we couldn't
speculatively share the resource like images do because imported documents are
mutable.

Hmm...
