I am running a flex application using flex builder and using
the fileref.upload() to upload a file to the sever which is also
located on the same machine, accessible through one of the ports.
Do I need a cross-domain policy?
Because I read the following from Programming ActionScript
3.0 Reference on the Adobe website...
"Uploads and downloads are not allowed if the calling SWF
file is in the local-with-filesystem sandbox. By default, a SWF
file may not initiate an upload to, or a download from, a server
other than its own. A SWF file may upload to, or download from, a
different server if that server provides a cross-domain policy file
that grants permission to the domain of the invoking SWF file."
In what cases will the upload work and which ones will it
not? I am confused.
