Figure out why browser caches aren't updating for new website

[myShoggoth]

I've seen it myself and it has been reported by many, I often have to control-refresh to get the new site. Is there something we need to add to the metadata of the site to tell browsers to clear the cache or limit it?

Yeah, usually you have to configure your web assets build too prepend a hash of the bundle's content to the filename, so that when the content changes, the path of the static asset in the HTML changes too, which is a nice cache-busting technique

Do any web experts know if there's some server setting (that perhaps goes to the browser in an HTTP header) that causes the browser to not bother looking for page changes? If I change a page on my own personal website then a simple refresh (not even a Ctrl-refresh, let alone deleting worker processes!) is enough to get the new page. It makes me wonder if something is misconfigured on the server.

Maybe we can just ask IOHK? I've hit the original page again today, served from Netlify, so maybe CDN configuration issues at play here as well?

Best practice is as follows

Routes to pages need a no-cache header, so the browser always fetches the html and never caches it.

All routes to static assests should be set to cache with an infinite ttl, then the assests links need to contain a hash of themselves to force redownload and recache when it changes.

I don't know what GitHub.io exposes for header controls, but if you like I can furnish nginx config that embodies the best practices mentioned above.

I can't get the new page at all. Just the old one, every time.

I need to do a control-refresh (on windows) to get the new stuff.

It's a service worker: #61 (comment)

I'm seeing this as well. I get what I assume is the older design (solid purple background), and navigation is completely broken. When I Shift-Refresh, I get what I guess is the new design (white background) and navigation works again. But Refresh again reverts to the old design and broken navigation. I haven't yet tried killing the service worker, but I have rebooted my machine several times since my visit to the old design, and it's still broken, so I can't imagine it's an old process causing it. I'll investigate and let you know.

It looks like this will be fairly widespread, judging from the number of reports and the fact that I didn't do anything unusual except visit the page several times.

Okay, unregistering the service worker worked and fixed the site for me. Just stopping it did not (as I expected).
