Can I just check that this is not possilbe due to the security model please?
I am trying to read in a file that is either outside of the server root or is protected by something like .htaccess and so that it can not be served out by the server. This file would contain a key that would be used in an authentication mechanism and hence can not be made available for access vias http, https etc.
If the http server won't serve the file, then Flash will have no way to access it via http.
That's what I thought. Thanks for the confirmation.
