Wow. Pretty, uh, interesting.
Why not just have XmlHttpRequest configurable to not share cookies, not
share auth, not accept anything but xml, etc.?

So you would use POST rather than GET just in case an unsecured web
application were contacted?
In the situation that an unsecured web application were contacted, how often
would a POST potentially modify data compared to a GET? (like
http://www.sillyexample.org/folder?id=27&operation=delete - often no content
body is required, and likely the content-type is unchecked anyway).
A poorly written server-side application is doomed no matter what, so you
might as well use a safe HTTP request method.

That doesn't sound good. What particular situations are bad? Re-direction
makes servers easier to support and maintain.

That makes sense, no information leakage.

And you wouldn't use caching but you'd like to avoid a denial-of-service

Do you mean client-side applications (the browser) or the server side?

Pretty standard stuff - I've done the same with XmlHttpRequest, and I think
lots of folks have.
