This extension must be configured with one of the following type URLs:

{
  "alternate_protocols_cache_options": "{...}"
}
alternate_protocols_cache_options

(config.core.v3.AlternateProtocolsCacheOptions) If set, causes the use of the alternate protocols cache, which is responsible for parsing and caching HTTP Alt-Svc headers. This enables the use of HTTP/3 for upstream servers that advertise supporting it. TODO(RyanTheOptimist): Make this field required when HTTP/3 is enabled via auto_http.
