Flex Uploading Issue

Question

Hi,
I am having great trouble with Flex and ColdFusion when it
comes to
uploading. I can upload fine to a server with no
authentication set
up but as soon as I start to upload using FileReference and
UrlRequest to a server with authentication from cflogin
problems
occur. Basically it fails silently, it displays progress in
the
upload and that the upload was successful but my files is not
there.
I have check all my scripts and location for the file upload
and it
just aint happening. I have tested a simple cfm upload form
and hit
that fine, uploaded and can write to files also on the remote
server
so I know thats set up fine.
So after much googling I have found that when using
FileReference for
uploading the upload will use a new browser session to upload
the
files and therefore remove all session variables!!! Arrrrggh!
So my
work around has involved grabbing the session.URLToken,
sending that
into my Flex app and then when I call the upload cfm script
pass the
session.URLToken variables in the url string like so:
request = new URLRequest();
chosenFile = fr.name;
request.url = UPLOAD_URL+"?"+sessionVars;
Problem is it still doesnt work?
(a) I dont know if that is enough to satisfy cflogin criteria
i.e. do
I need to set anything in the upload.cfm page to say that
these are
the session variables.
(b) another weird thing is that if it is starting a new
browser
session why am I not presented with my login panel as
requested by my
Application.cfc?
Any one else suffered here or could make a suggestion please
Simon
P.S. I understand this is not an issue in IE only Firefox
(and Safari I have discovered)!

Answer 1

This is most peculiar cos I am definitely not hitting the
server side script (which I thought was due to session clearing)
but may not be then cos I get no error like you state and also my
login window doesn't rear its ugly head. But I DO know for certain,
the server script is not being hit, cos I run a simple write action
to append a log file and that is not even running???
And yeh uploading from a mac os x system. However, it fails
in FireFox on the PC also.

Check this:

Through Flash's FileReference and FileReferenceList classes,
you can create a powerful file uploader that allows the user to
upload multiple files with a single form element. But beware:
unless the user happens to be using IE, the upload will use a new
browser session to upload the files. This means that if you require
that a user be authenticated before uploading something (and you
better be), the upload won't work - the request will be forwarded
to the login form, or to wherever your system forwards unauthorized
requests. This is a maddening bug to track down, and there is
nothing you can do to make Flash use the right session. The work
around is to send the session cookie in the url and, on the server
side, use that to override the new (and wrong) session cookie sent
by Flash
