What data formats can AJAX transfer?

Question

I\'m new to AJAX, but as an overview I\'d like to know what formats you can upload and download. Is it limited to JSON or XML or can you even send binary types like MP3 or UTF-8

Answer 1

You can move anything that can be sent over HTTP. There are restrictions about the call being made to the same domain as the page loaded from, but not on the content of the transfer. You can do either GET or POST transactions too.
