Thanks to several people I've managed to track down why the facebook issues
are suddenly appearing and why its intermittent.
On the sometimes works sometimes doesn't problem. facebook.com does
User-Agent header checks and sends back one of four pages.
1) a generic page saying 'please use another browser'.
2) a redirect to login for each of IE, Firefox and Safari
3) a home page (if cookies sent initially)
going through the login redirects to the page also presented at (3) above.
The home page is the real problem. When cookies are presented it ships
without Content-Length (fine).
When they _are_ present, ie after the user has logged in it ships with
Content-Length: 18487 and data size of 18576.
