Are you using Amazon S3, Google Cloud Storage, or some other object storage provider to serve your images and other assets? Cloudflare doesn't automatically cache these valuable resources! That's what Cassette is for.
Cassette 🐇 speeds up your site and 💰 saves you money on your object storage provider bill.
How to Install
Powered by Cloudflare
Cloudflare offers DDoS protection, a global CDN, SSL certificates, and a lot more cool stuff for free. You should probably use it.
Cassette only takes a few minutes to install on your site but additional required configuration is necessary for Cassette to work properly. The installation page covers the basics but we'll cover more here.

OPTIONAL Object Storage Pathname
This option is useful if your Object Storage bucket has a pathname. Otherwise, ignore it. Some buckets are intialized with a path-style URL - like http://storage.googleapis.com/yoursite.
In this case,

Object Storage Origin should be changed to
Asset Subdomain. Once you've updated your links, ensure Cassette is working by reloading the page and inspecting the cf-cache-status header on requests to
Let's say your Assets Subdomain is assets.yoursite.com and your Object Storage Origin is yoursite.s3.amazonaws.com and your site contains a cute picture of your cat. The HTML for your cat picture probably looks something like
<img src="https://yoursite.s3.amazonaws.com/mycat.jpg" />. This needs to be updated to
<img src="https://assets.yoursite.com/mycat.jpg" />
Generally, any references to
yoursite.s3.amazonaws.com should be updated to
