Go 1.23 changed
[`net/http.ServeContent`](/pkg/net/http#ServeContent),
[`net/http.ServeFile`](/pkg/net/http#ServeFile), and
[`net/http.ServeFS`](/pkg/net/http#ServeFS) to
remove Cache-Control, Content-Encoding, Etag, and Last-Modified headers
when serving an error. This behavior is controlled by
the [`httpservecontentkeepheaders` setting](/pkg/net/http#ServeContent).
Using `httpservecontentkeepheaders=1` restores the pre-Go 1.23 behavior.

	if cannotHeal && quorumETag != "" {
		// This is an object that is supposed to be removed by the dangling code
		// but we noticed that ETag is the same for all objects, let's give it a shot
		cannotHeal = false
	}

	if !latestMeta.Deleted && !latestMeta.IsRemote() {
		// check if there is a part that lost its quorum

	// create xlStorage test setup
	xlStorage, _, err := newXLStorageTestSetup(t)
	if err != nil {

    this was case sensitive. This change should also make it easier to configure
    certificate pinning for internationalized domain names.
 *  Fix: Don’t crash on non-ASCII `ETag` headers. Previously OkHttp would reject
    these headers when validating a cached response.
 *  Fix: Don’t allow remote peer to arbitrarily size the HPACK decoder dynamic
    table.
