http-cookie-auth isn't at all limited to AJAX uses!
See http://hg.ltgt.net/http-cookie-auth/raw-file/tip/research.html

There are many frameworks out there where you settle for an auth
mechanism and it gets applied to each and every resource (URL) in your
app (e.g. ASP.NET, Alfresco's WebScripts framework, etc.)

For instance, we're using a custom scheme very similar to Cookie (it
also allows the credentials to be passed in an Authorization header,
for use with... AJAX! yes, AJAX calls use Authorization and cookies
are only used for non-AJAX requests, in our case, the admin section)
in an Enterprise app (this means admins cannot use Opera pre-10, but
we're only actually targeting IE6 only):
Demo AJAX app: https://ubic.atolcd.com/
Demo "web 1.0" admin interface:
https://ubic.atolcd.com/alfresco/us/ubic/admin/ (the login screen is
returned in a 401 response)
