Access control allow origin cloudfront4/21/2024 ![]() ![]() Congratulations! ReferencesĪt Box UK we have a strong team of bespoke software consultants with more than two decades of bespoke software development experience. If everything has worked as it should, you should now be able to access your files cross-domain from CloudFront. Click Yes, Edit to save and then wait for CloudFront to propagate the change about 20 mins to half an hour. Select ‘Origin’ in the left-hand list and click Add to move it to the right-hand list. Change the Forward Headers dropdown to Whitelist. Go to the Behaviours tab, click the behaviour (if you have more than one, you’ll need to do the following for all of them) and click Edit. Select the CloudFront distribution that’s associated with the S3 bucket you changed above in the AWS console. Step 2: enable Header Forwarding in CloudFront So the problem were in API, because it didn't properly responding with header 'Access-Control-Allow-Origin' (AWS Lambda + API Gateway) even if cURL command works. There are more options available as listed at Amazon’s How do I enable Cors resource. After few hours I found, that my API is not responding with headers 'Access-Control-Allow-Origin' : '' only within browser with axios.POST(). Add an allowed method tag for each HTTP method you want to use (GET, POST, PUT, DELETE). Replace ‘YOUR DOMAIN HERE’ with your domain (wildcards are allowed). The browser was caching the resources for 1 domain, then when navigating to another some asset files did not contain the Access-Control-Allow-Origin header. This is a very basic CORS configuration for one domain. Example CORS configuration YOUR DOMAIN HERE GET * ![]() Paste your CORS config in there and press save. After you create an origin access control, you can add it to an origin in a CloudFront distribution so that CloudFront sends authenticated (signed) requests to the origin. You’ve now got a popup called ‘CORS Configuration Editor’ with a big text box in it. Creates a new origin access control in CloudFront. You should see a button labelled ‘Edit CORS Configuration’ or something similar. Click the Properties tab then open the Permissions area. Go to your S3 bucket in the AWS (Amazon Web Services) console and select it. It assumes that you have an S3 bucket set up and associated with a CloudFront distribution. This is a really basic how-to for enabling cross-domain access. This is a fairly normal occurrence, especially with a CDN like CloudFront, so you’d think it’d be well documented, right? No? Well it will be after this. I recently had to allow cross-domain access in Amazon’s CloudFront service for some XML and closed caption files. Enabling cross-domain access in CloudFront ![]()
