Apologies for the late comments - I belatedly realized the close of
comments on this was June 3.
I've been discussing some of this internally within Oracle USA and
within the OWASP mail lists, and would like to make a suggestion.
We're very happy with the mention in the April 15th spec:
/Apart from requirements affecting security made throughout this
specification implementations /may/, at their discretion, not expose
certain headers, such as HttpOnly cookies.//
/http://dev.w3.org/2006/webapi/XMLHttpRequest/#security
However, we'd like to see even stronger language here. We think it
should be *recommended *or even better yet *required *that
XMLHttpRequest not see these headers of HttpOnly cookies. The fact
that XMLHTTPRequest can currently see these cookies greatly undermines
the security value of this flag.
Thanks,
