I've been working with some client side flash developers recently and we came across an unusual error that was being thrown in a Flex application when we were sending a webservice request to a Coldfusion server.

The error was "Security error accessing URL". I thought I'd overcome this a long time ago by using the cross-domain.xml file to allow server access to services.

It appears that there is a security issue with Flash 9 that requires the following line to be added to the CrossDomain.xml file:

I'm guessing that it is enabling access for SOAP requests to any remote services on that server.

Most of us are familiar with the AJAX post() and getJSON() methods of remotely calling and passing around data, I use them with abundance when building applications. One thing I had not considered until recently is that all my AJAX Http requests are usually internal to that application, which also means they are on the same server and domain.

I recently jumped into a project where the application spanned 24 domains, and had been developed to use a core component library to help code re use. The problem with this arose when you are on one domain (www.domain1.com) and you want to make a request to a different domain (www.domain2.com). You encounter something called the 'same-Origin' policy.

This article deals with how to create a proxy to handle cross site AJAX http Requests.

I've recently convinced a colleague at work to switch from his iPhone to the Android platform. His one caveat was that you could get hold of the same Applications, or at least Applications that would provide the same functionality.

Almost all the Applications he used we available on both platforms, the most process to replicate is synchronising your phone with iTunes. Obviously the iPhone does this out of the box, but how can you do this on the Android platform?

The answer is DoubleTwist a free Application that can manage synchronising removable disks with iTunes and Windows Media player.
