request to <code>http://a.com</code> will be upgraded to <code>https://a.com</code>, but the fetch
will fail. A fallback request will be initiated to <code>http://a.com</code>.

<p id=example-https-upgrade-allowlist class=example><code>site.test</code> serves
<code>http://site.test</code> but refuses connections on <code>https://site.test</code>. Upon
first request and fallback to <code>http://site.test</code>, the user agent stores the hostname
in an allowlist with an expiration time of 7 days. In a future request, if <code>site.test</code>
is still in this allowlist, the user agent will not upgrade <code>http://site.test</code> to
<code>https://site.test</code>. The user agent will also set the new expiration time of the
allowlist entry for <code>site.test</code> to 7 days from now.

<p id=example-https-upgrade-ports class=example><code>a.com</code> serves
<code>http://a.com:8080</code>. When a site is served from a non-default HTTP port, it's unlikely
that the corresponding HTTPS URL is served from the default port either. Therefore, the user agent
doesn't upgrade requests to <code>http://a.com:8080.</code>

<p id=example-https-upgrade-redirect-loop class=example><code>a.com</code> serves
<code>http://a.com</code> and <code>https://a.com</code>. The latter redirects to the former.
An eligible request to <code>http://a.com</code> will be upgraded to
<code>https://a.com</code> and will be redirected back to <code>http://a.com</code>.
The user agent will detect this as a redirect loop, treat it as a failed upgrade and initiate a
fallback navigation to <code>http://a.com</code>.
