### CloudFront Tips
- While the most common use is for users to browse and download content (GET or HEAD methods) requests, CloudFront also supports ([since 2013](https://aws.amazon.com/blogs/aws/amazon-cloudfront-content-uploads-post-put-other-methods/)) uploaded data (POST, PUT, DELETE, OPTIONS, and PATCH).
- You must enable this by specifying the [allowed HTTP methods](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesAllowedHTTPMethods) when you create the distribution.
- Interestingly, the cost of accepting (uploaded) data [is usually less](https://aws.amazon.com/cloudfront/pricing/) than for sending (downloaded) data.
- In its basic version, CloudFront [supports SSL](http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/SecureConnections.html) via the [SNI extension to TLS](https://en.wikipedia.org/wiki/Server_Name_Indication), which is supported by all modern web browsers. If you need to support older browsers, you need to pay a few hundred dollars a month for dedicated IPs.
- 💸⏱Consider invalidation needs carefully. CloudFront [does support invalidation](http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Invalidation.html) of objects from edge locations, but this typically takes many minutes to propagate to edge locations, and costs $0.005 per request after the first 1000 requests. (Some other CDNs support this better.)
- Everyone should use TLS nowadays if possible. [Ilya Grigorik’s table](https://istlsfastyet.com/#cdn-paas) offers a good summary of features regarding TLS performance features of CloudFront.
