When uploading a file in an ezobject with an attribute file we try to load the file with a video html tag in a template.
We have eZ Dfs mode enabled.

If we try on Google Chrome, the video won't be downloading (the request is canceled, see screenshot attached).

If we move the file out of ezpublish (and ouf of index_cluster.php) and we load it in Google Chrome it works fine (on the same server).
