Need alternative to POST data using navigateToURL that works with Pepper Flash plugin - actionscript-3

Question

As most people know, Google messed several flash applications after starting using Pepper Flash plugin in Chrome.
I'm getting the same problem, but it can't be solved with external interface call, as I need to post data using POST, to a php file.
My application basicaly takes a screenshot, and post to a php file. Worked fine before, but now with Pepper Flash, nothing happens.
This is the piece of code that POSTs the data.
jpgURLRequest.method = URLRequestMethod.POST;
jpgURLRequest.data = jpgStream;
navigateToURL(URL_TO_THE_PHP_FILE, "_self");
Is there a workaround for this? My website that uses this application have thousands visitors daily, and most users woudn't know how to disable pepper flash.
thanks.

To upload image, you will need URLLoader, image encoding algorithm, and some contract(names of variables in POST's body, encoding algorithm, etc) with you server-side
var urlRequest : URLRequest = new URLRequest();
var urlLoader : URLLoader = new URLLoader();
var urlVars : URLVariables = new URLVariables();
//Take from the image bytes, for example with JPEGEncoder
//Endoce ByteArray for example with Base64
//If image is big, you can split on several parts
urlVars.image = Base64.encode(imageData);
urlRequest.url = $snapshotUploadURL;
urlRequest.method = URLRequestMethod.POST;
urlRequest.data = urlVars;
// create the image loader & send the image to the server;
urlLoader.addEventListener(Event.COMPLETE, onComplete);
urlLoader.load(urlRequest);
BloodyCrypto is very helpful library for this task.
