First, don't put spaces in your HTML attributes. This is correct:
Code:
<form action="http://www.example.com" method="post">
Second, what does your .htaccess look like?
Related note: I'd say the most common reason POST data is removed is due to a redirect / refresh. Verify that you aren't performing any such actions, and that your .htaccess isn't either.
