Allow AJAX GETs from Amazon S3? (Access-Control-Allow-Origin)

Question

I\'m storing JSON objects in Amazon S3, and I\'d like to load that data directly from S3 from Javascript. My GET looks pretty generic:

$.ajax({
    \'type\':         


        

Answer 1

For anyone struggling with this issue, as others say you must force S3 to respond with CORS headers by adding these lines to your CORS configuration:

http://*
https://*

BUT, you then must clear your browser file cache as the old headers on the requested resource are stored. In Chrome, find the Clear Browsing Data option and then choose to clear the file cache. A hard reload will not clear certain files. If you prefer to only clear the file cache only for the current site, this answer explains how to do just that.

This was the gotcha for me.
