Subject Re: whitelist as a plugin
Date Tue, 08 Jul 2014 16:54:23 GMT
I'm in agreement with Andrew on this one.  If we can get CSP working,
that's a far better solution than our Whitelist, which was done
because it was needed at the time for the enterprise use case that IBM
had.  I don't think we're ever going to stop are users from doing dumb
things like including thirdpartyadnetworkthatdoesnoteusehttps.js in
their apps any time soon, but they'll have to jump through more hoops
to do dumb things, and making dumb things harder is a good thing.
