In the enterprise Intranet, there is this web application that is being served through Nginx. Nginx is generating the ETag HTTP header as expected.

However, upon re-visiting or refreshing the web application, the browser (Chrome or Edge) is not sending the ETag in the If-None-Match HTTP request header.

Is this a setting somewhere? Or how can I start to look for the problem? Many thanks.
