    Why would you restrict ports if you restrict to the originating
server?   If they want to hack themselves let them.  BTW you
absolutely should not allow even HTTP requests to anything but
the originating server from Script, otherwise they can browse
a persons intranet, (links are different because the originating file
doesn't get access to the new content).

    Sure, this would be totally reasonable.

    Sorry, I totally disagree, this is still a very useful interface.
Not everything on the web is or should be HTTP.  There are many
cases where you want long lived connections with Bi-directional
data.
