Best practices for setting environment based static variables?

[a-fro]

I have a set of static string variables that hold the url location of modules in a project. These locations change depending on whether I'm building for development, staging or production.

What's the best way to set static variables in this way?

I don't know if this is best practice, but here's the solution I've come up with.

The root domain is accessible within the swf via a node on a loaded xml file. So I created a simple method that sets a url variable based on that domain node.

The domain-based url variable is then used within the static string variables that define the location of the modules.

Simplified like so:

var domain:String = xml.node.value;

static var bucketLocation:String = getLocation()

static var moduleLocation:String = bucketLocation + "modulename.swf";

function getLocation():String

{

     var loc:String

     switch (domain) {

          case stagingUrl:

              loc = "pathToAmazonStagingBucket";

               break;

          case productionUrl:

               loc = "pathToAmazonProductionBucket";

               break;

     }

}
