I registered some odd behavior regarding cookies when accessing "hellofood.qa" in Safari for OSX.
The website tries to set two cookies with domain ".hellofood.qa" so that they work with subdomains as well. But these cookies never appear on the browser cookie inspection and aren't served back on subsequent requests.
The exact same code with "hellofood.cl" works without problems as the browser accepts the ".hellofood.cl"' cookies.
Tested with latest Nightly Build: r168650.
I cannot reproduce this with Safari 7.0.4 on OS X 10.9.3.
Because of this issue, currently hellofood.qa no longer serves cookies with .hellofood.qa domain.
Will try to build a page with an use case that is reproducible but doesn't break the site.
