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.

An HTTP request with the request header If-None-Match with a value of "65f32975-32648" was sent, and an HTTP 304 was responded with.

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.
