APM redirect to /my.policy stripping POST data

Some of the question was truncated. The question was: I have a condition where an unauthenticated user sends a POST request to a F5 virtual server running Access Policy. As part of the authentication process, the F5 redirects the original POST to /my.policy which, in turn, responds with HTML that contains a HTML form that gets automatically submitted requesting the original content. This time without the POST data! Has anyone encountered this?
