  // This is the list of load flags and their values. For the enum values,
  // include the file "net/base/load_flags.h".
  //
  // Here we define the values using a macro LOAD_FLAG, so it can be
  // expanded differently in some places (for example, to automatically
  // map a load flag value to its symbolic name).
  
  LOAD_FLAG(NORMAL, 0)
  
  // This is "normal reload", meaning an if-none-match/if-modified-since query
  LOAD_FLAG(VALIDATE_CACHE, 1 << 0)
  
  // This is "shift-reload", meaning a "pragma: no-cache" end-to-end fetch
  LOAD_FLAG(BYPASS_CACHE, 1 << 1)
  
  // This is a back/forward style navigation where the cached content should
  // be preferred over any protocol specific cache validation.
  LOAD_FLAG(PREFERRING_CACHE, 1 << 2)
  
  // This is a navigation that will fail if it cannot serve the requested
  // resource from the cache (or some equivalent local store).
  LOAD_FLAG(ONLY_FROM_CACHE, 1 << 3)
  
  // This is a navigation that will not use the cache at all.  It does not
  // impact the HTTP request headers.
  LOAD_FLAG(DISABLE_CACHE, 1 << 4)
  
  // If present, causes certificate revocation checks to be skipped on secure
  // connections.
  LOAD_FLAG(DISABLE_CERT_REVOCATION_CHECKING, 1 << 5)
  
  // This load will not make any changes to cookies, including storing new
  // cookies or updating existing ones.
  LOAD_FLAG(DO_NOT_SAVE_COOKIES, 1 << 6)
  
  // Do not resolve proxies. This override is used when downloading PAC files
  // to avoid having a circular dependency.
  LOAD_FLAG(BYPASS_PROXY, 1 << 7)
  
  // Requires EV certificate verification.
  LOAD_FLAG(VERIFY_EV_CERT, 1 << 8)
  
  // This load will not send any cookies.
  LOAD_FLAG(DO_NOT_SEND_COOKIES, 1 << 9)
  
  // This load will not send authentication data (user name/password)
  // to the server (as opposed to the proxy).
  LOAD_FLAG(DO_NOT_SEND_AUTH_DATA, 1 << 10)
  
  // This should only be used for testing (set by HttpNetworkTransaction).
  LOAD_FLAG(IGNORE_ALL_CERT_ERRORS, 1 << 11)
  
  // Indicate that this is a top level frame, so that we don't assume it is a
  // subresource and speculatively pre-connect or pre-resolve when a referring
  // page is loaded.
  LOAD_FLAG(MAIN_FRAME, 1 << 12)
  
  // If present, intercept actual request/response headers from network stack
  // and report them to renderer. This includes cookies, so the flag is only
  // respected if renderer has CanReadRawCookies capability in the security
  // policy.
  LOAD_FLAG(REPORT_RAW_HEADERS, 1 << 13)
  
  // Indicates that this load was motivated by the rel=prefetch feature,
  // and is (in theory) not intended for the current frame.
  LOAD_FLAG(PREFETCH, 1 << 14)
  
  // Indicates that this is a load that ignores limits and should complete
  // immediately.
  LOAD_FLAG(IGNORE_LIMITS, 1 << 15)
  
  // Indicates that the operation is somewhat likely to be due to an
  // explicit user action. This can be used as a hint to treat the
  // request with higher priority.
  LOAD_FLAG(MAYBE_USER_GESTURE, 1 << 16)
  
  // Indicates that the username:password portion of the URL should not
  // be honored, but that other forms of authority may be used.
  LOAD_FLAG(DO_NOT_USE_EMBEDDED_IDENTITY, 1 << 17)
  
  // Send request directly to the origin if the effective proxy is the data
  // reduction proxy.
  // TODO(rcs): Remove this flag as soon as http://crbug.com/339237 is resolved.
  LOAD_FLAG(BYPASS_DATA_REDUCTION_PROXY, 1 << 18)
  
  // Indicates the the request is an asynchronous revalidation.
  LOAD_FLAG(ASYNC_REVALIDATION, 1 << 19)
