Fragments are not allowed in the HTTP request URI and are not transmitted. They 
are allowed in the Location header which is not an issue.

Subject: Re: [OAUTH-WG] OAuth 2.0 Bearer Token specification draft -01

I was reading the specifications, mainly the new related to the security issues.

One thing is pointed out in the security summary is related to the fact that the
token should not be in the URL. So, here come some of my doubts on the the
user agent flow, where it is set on the URL fragment. Even more, if working
only on the client side, I suppose I should save the token somewhere and the
cookie, secure one, should be the option. There should also be the possibility
to save it on a JavaScript variable, but this means I'll only use AJAX style web
page definition (no reloads).

If possible, I would love to have some clarifications on the the user agent flow
security definition. As far I've searched on the web several project do not use 
it
because they think "its not secure", so I would love to understand more about.
