What I am trying to accomplish is to upload some binary data, specifically a ByteArray representing a PNG image, to a server using the URLLoader class in conjunction with URLRequest. When I set the contentType property of the URLRequest to 'multipart/form-data' instead of the default, the call to urlLoader.load() results in a security exception. When I leave the contentType property as the default, it works fine, but takes a long time (proportional to the length of the PNG file) to upload the file to the server. So, my question is WHY am I getting this security exception? And how can I avoid

I have two files: ./img/mypic.png ./js/help/targets/target.js In target.js: <img src={require("../../../img/target.png")} /> With webpack.config.js: 14 module: { 15 loaders: [ 16 { test: /\.js$/, loader: 'jsx-loader?harmony' }, 17 { test: /\.css$/, loader: 'style-loader!css-loader' }, 18 { test: /\.(png|jpg|jpeg|gif|woff)$/, loader: 'url-loader?limit=8192' }, Which compiles the image into ./[hash].png . Now, I use react-router , so I'm at /help/targets/target and webpack is giving the image this path /help/targets/[hash].png where hash is a sha1 sum. I would prefer if it gave it the path /

Is there a way to access the response headers from an HTTP result when using Flash/Flex's URLLoader ? Setting the request headers is possible, as is accessing the response code , but getting a hold of the actual response headers seems to be conspicuously lacking... Specifically, I would like to get a hold of the Last-Modified response header. Oops. Answering my own question here, but AIR introduces the URLLoader.httpResponseStatus event which includes a responseHeaders property (plus a responseURL property for brownie points). Thankfully my question was for an AIR application, so that solves
