Been a while since i have shared any coding tips, but here is one for those Actionscript 3 Coders out there. Its a helper function that splits a URL up into its different parts using RegExp.

public static function dissectURL(url:String) : Object


var keys : Array = [“source”, “protocol”, “authority”, “userInfo”, “user”, “password”, “host”, “port”, “relative”, “path”, “directory”, “file”, “query”, “anchor”];

var hostExtractPattern:RegExp = /^(?:([^:/?#]+):)?(?://((?:(([^:@]):?([^:@]))?@)?([^:/?#])(?::(d))?))?((((?:[^?#/]/))([^?#]))(?:?([^#]))?(?:#(.*))?)/;

var o : Object = hostExtractPattern.exec(url);

var r : Object = new Object();

for (var i:int = 0; i < keys.length; i++) { r[keys[i]] = o[i];Â Â Â }

return r;

An example of its use would be:
var protocol : String = dissectURL(“").protocol;

It would trace “http”.
