I recently wrote a simple data store web application in Python (in the process learning a lot of Python) connected to a separate Javascript only client on a different server. In the process I learned a lot more than I ever wanted to about cross origin resource sharing (CORS). This is a set of standards that allow services from different websites to interoperate but without compromising security. This is a great article from a couple of years ago on CORS, just shared today by Simon Willison. If you're developing web technology, you need to know about CORS.
