Google PageSpeed Insights is giving me one of the criterias that requires some work:
Leverage browser caching
I’m using Amazon S3 + CloudFront to serve my static assets. To set the HTTP headers for Cache-Control, I used an application on Windows called “CloudBerry Explorer for Amazon S3”.
The application lets me manage many different types of server storage, including AWS S3. To update multiple file headers:
- In CloudBerry Explorer for Amazon S3, right click the file(s) and select: Set HTTP Headers
- Click: Add
- Use the following settings:
- Http Header: Cache-Control
- Value: max-age=604800
max-age is in seconds. Converting 604800 seconds will be equivalent to 1 week.
