JavaScript function to expand virtually any shortened/masked URL using the LongURL.com API v2. If a callback is passed the request will execute asynchronously, otherwise the function will block until a response has been received. Uses the "longURLAPICall()" function from http://gist.github.com/KuroTsuto/8447974

Expand Shortened URL

expandShortenedURL = function( str_shortenedURL, fn_callback ) {
	if( str_shortenedURL.indexOf( "http://" ) < 0 )
		str_shortenedURL = "http://" + str_shortenedURL;

	return longURLAPICall( "expand", { title: 1, url: str_shortenedURL }, fn_callback );		
};
