+/**
+ * Each test is run twice: once using etag/If-None-Match and once with
+ * date/If-Modified-Since.  Each test run gets its own URL and randomized
+ * content and operates independently.
+ *
+ * The test steps are run with request_cache.length fetch requests issued
+ * and their immediate results sanity-checked.  The cache.py server script
+ * stashes an entry containing any If-None-Match, If-Modified-Since, Pragma,
+ * and Cache-Control observed headers for each request it receives.  When
+ * the test fetches have run, this state is retrieved from cache.py and the
+ * expected_* lists are checked, including their length.
+ *
+ * This means that if a request_* fetch is expected to hit the cache and not
+ * touch the network, then there will be no entry for it in the expect_*
+ * lists.  AKA (request_cache.length - expected_validation_headers.length)
+ * should equal the number of cache hits that didn't touch the network.
+ *
+ * Test dictionary keys:
+ * - state: required string that determines whether the Expires response for
+ *   the fetched document should be set in the future ("fresh") or past
+ *   ("stale").
+ * - vary: optional string to be passed to the server for it to quote back
+ *   in a Vary header on the response to us.
+ * - cache_control: optional string to be passed to the server for it to
+ *   quote back in a Cache-Control header on the response to us.
+ * - redirect: optional string "same-origin" or "cross-origin".  If
+ *   provided, the server will issue an absolute redirect to the script on
+ *   the same or a different origin, as appropriate.  The redirected
+ *   location is the script with the redirect parameter removed, so the
+ *   content/state/etc. will be as if you hadn't specified a redirect.
+ * - request_cache: required array of cache modes to use (via `cache`).
+ * - request_headers: optional array of explicit fetch `headers` arguments.
+ *   If provided, the server will log an empty dictionary for each request
+ *   instead of the request headers it would normally log.
+ * - response: optional array of specialized response handling.  Right now,
+ *   "error" array entries indicate a network error response is expected
+ *   which will reject with a TypeError.
+ * - expected_validation_headers: required boolean array indicating whether
+ *   the server should have seen an If-None-Match/If-Modified-Since header
+ *   in the request.
+ * - expected_no_cache_headers: required boolean array indicating whether
+ *   the server should have seen Pragma/Cache-control:no-cache headers in
+ *   the request.
+ * - expected_max_age_headers: optional boolean array indicating whether
+ *   the server should have seen a Cache-Control:max-age=0 header in the
+ *   request.
