Revision 9f72b689165309d4b959f3dbc724f18fe9a77111 authored by Mike West on 05 April 2018, 12:29:12 UTC, committed by Chromium WPT Sync on 05 April 2018, 12:29:12 UTC 
Add a runtime flag to restrict AppCache to secure contexts.
 
This patch adjusts the `SecureContext` IDL attribute to take an argument,
as we need to restrict the relevant bits and pieces to secure contexts
iff a specific flag is set. We'll unfortunately need to keep that in place
until and unless we decide that we can reasonably remove an enterprise
opt-out.
