Comment 1 Simon Pieters 2012-06-04 13:37:25 UTC 
When failure mode is "fail" and mode is "No CORS", we shouldn't fetch anything at all but just fail directly.
Comment 2 Simon Pieters 2012-06-05 07:31:57 UTC 
Similarly, if /default/ is "fail", and /mode/ is "No CORS", and /URL/ is a same-origin URL that redirects to a different-origin URL, the redirect shouldn't be followed but should fail at that point.

This bug was cloned to create bug 18215 as part of operation convergence.
Comment 4 Ian 'Hixie' Hickson 2012-07-27 03:12:50 UTC 
Can you elaborate?
Comment 5 Simon Pieters 2012-08-15 09:33:01 UTC 
When /default/ is "fail", we don't want to waste network resources on fetches we know we're not going to accept. This also applies in case of redirects.

This came up as part of implementing <track>.
