Supporting IE is still a thing.

An interesting tidbit I came across today.

Apparently Internet Explorer won’t make an XMLHttpRequest from a given security zone into a more secure zone. It makes perfect sense, but I spent a ton of time figuring out that it wasn’t a CORS issue. I even spent a bunch of time looking into P3P – blech. I didn’t even realize the sites were in different zones until I had a eureka moment.
