I have a Flex app that I'm trying to add "file preview" functionality to. I have a LinkButton in Flex that, when clicked, should open the file in a new browser window. I found a helpful actionscript class that properly formats the POST data to pass the file to an HTML page. The files I want to preview are being stored in the database, and I'm passing the through the POST data as a ByteArray. The file POST data is put into a URLRequest, which is sent to the HTML page through a URLLoader.
Here's what my POST request looks like:
--lljcuqjclcnyicgrmwexayhafmkhiwfx Content-Disposition: form-data; name="Filename" arrows.png --lljcuqjclcnyicgrmwexayhafmkhiwfx Content-Disposition: form-data; name="Filedata"; filename="arrows.png" Content-Type: image/png ?PNG "image information as ByteArray" --lljcuqjclcnyicgrmwexayhafmkhiwfx Content-Disposition: form-data; name="Upload" Submit Query --lljcuqjclcnyicgrmwexayhafmkhiwfx--

spit the data back as a base64 string and concat to build a data url to use as the .src of an iframe.
echo "data:" . $mimeType . ";" . $base64fileData ;
if you want 100% compatibility, you might just have to iframe the server response and give up on JS doing it for you.
