NOTE for testing No-Vary-Search-Header:
- If `params` is set to true, `expect=("dispatch" "uuid")` must be specified.
Otherwise:
- The same HTTP Cache will be used by other tests, which are supposed
to be distinguished by uuid.
- The test utility cannot get the server's states because UA will use the HTTP
Cache instead of sending a new request to server to ask for the latest state.
- Do not test not_cached cases and cached cases within one test. Test infra
checks the number of requests and responses without considering if the
previous responses should be served from cache or not.
