• I use a plugin which prefetches links when a user hovers over them to improve site speed. This works by adding a <link rel=prefetch url=”..”> to the page html, which is the standard for instructing the browser to prefetch content.

    The browser (Chrome) normally handles this request by sending a request which has a header titled “purpose”, with the value “prefetch”. However, with the PWA plugin active, whilst these requests are sent, the purpose header is missing.

    I’m just wondering if there’s a reason for this and if it can be added back in?
