Requirement
Using one of many online SEO checkers, I’ve found that one of the most prominent issue is a missing HTTP 301 redirect from www domain to the main one (https://www.marcoaguzzi.it to https://marcoaguzzi.it). Since the website is a static s3 bucket served by cloudfront, this can be achieved by using a Lambda@Edge function.
What’s a Lambda@Edge function?
In the AWS ecosystem, Lambda functions are small programs that can be invoked by a number of different callers. The Amazon motto is: “write the code and forget about the server”.
