P3P configuration troubleshooting

Problem:

Browser cannot access the full P3P policy file.

Solution:

When the p3p-element stanza entry is used to specify the location of a file containing the full policy, the browser attempts to access the file. The P3P specification does not require browsers to submit cookies with the request for the full policy. Internet Explorer 6 does not submit a session cookie when accessing the full policy.

Therefore access to the full policy must be granted to unauthenticated users. When the browser receives either a login form or a 401 error, modify the permissions on the full policy to allow access by unauthenticated users.
