What is this check, and why should you care

Using a long cache lifetime helps to ensure a high cache hit rate.

In order to get maximum points, your cache lifetime must be greater than or equal to 4 weeks. If your cache lifetime is less, then you will get some proportion of the score based on how close to 4 weeks you are.

Current cache lifetime is 31536000 seconds (1 year and 1 month).

What is this check, and why should you care

Using ETag identifiers is an easy way to ensure your visitors are always getting the most up-to-date version of the content. This mechanism allows caches to be more efficient and saves bandwidth, as a Web server does not need to send a full response if the content has not changed. HTTP 304 responses are used to indicate this is working.

No ETag header was found in the response.

See the Wikipedia page on ETag for more background.

In order to get maximum points, you need to have ETag identifiers and an HTTP 304 response must be received when using a valid If-None-Match request header.
