RE: [xml-dev] Cracking AJAX? Done yet?

In some cases the web services that are used by javascript clients are
also available to anyone else, or they are a special version of a widely
available web service.

There are likely to be all the same access restrictions on the data
available via a raw XMLHttpRequest that there would be on a regular page
that contained that data so if by "cracking" you mean getting
unauthorized access I wouldn't expect a free lunch (that said, given the
current fever it may be that the security model on some services used by
ajaxs apps has been rushed out the door).

Anecdotally json is used pretty widely so I wouldn't count on ajax realy
being XML under the hood.  I'd give it a more even distribution between
XML, json and roll-your-own formats (and I have no numbers to back this
up).
