Is there a single universal way to load all assets before using them? I am wanting to load some images, audio files, and a few .swf files before my app starts. Currently, I load the images by creating new <img> elements and setting the src to the image path, for the audio files I add the preload="auto" attribute in the <audio> tag and I perform an ajax request to load the .swfs.
Is there any problem (re some browsers not caching etc.) with the way I am currently loading my files and is there a 'best practices' way of collectively preloading all these file types before I display my content?
