[flexcoders] #2038: File I/O Error only in firefox

[Dennis Falling]

I searched the web and the group and found a thread going about this without
a resolution (started with msg. 88102).  Does anyone know a way around
this?  I need to allow the user to upload files over SSL, which works fine
from IE but explodes in Firefox.

Code:
var url:String =
Services.getCommandServiceURL(FileDelegate.UPLOAD_FILE_COMMAND);
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;
_file.upload(request,"fileData",false);

When run in Firefox, I get a flash exception:
Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.

Watching it in Wireshark I see the initial post, then a number of subsequent
lines "Continuation or non-HTTP traffic".

Thanks!
