+  // This is the default state.  It corresponds to a resource load that has
+  // either not yet begun or is idle waiting for the consumer to do something
+  // to move things along (e.g., the consumer of an URLRequest may not have
+  // called Read yet).
+  LOAD_STATE_IDLE,
+
+  // This state corresponds to a resource load that is blocked waiting for
+  // access to a resource in the cache.  If multiple requests are made for the
+  // same resource, the first request will be responsible for writing (or
+  // updating) the cache entry and the second request will be deferred until
+  // the first completes.  This may be done to optimize for cache reuse.
+  LOAD_STATE_WAITING_FOR_CACHE,
+
+  // This state corresponds to a resource load that is blocked waiting for a
+  // proxy autoconfig script to return a proxy server to use.  This state may
+  // take a while if the proxy script needs to resolve the IP address of the
+  // host before deciding what proxy to use.
+  LOAD_STATE_RESOLVING_PROXY_FOR_URL,
+
+  // This state corresponds to a resource load that is blocked waiting for a
+  // host name to be resolved.  This could either indicate resolution of the
+  // origin server corresponding to the resource or to the host name of a proxy
+  // server used to fetch the resource.
+  LOAD_STATE_RESOLVING_HOST,
+
+  // This state corresponds to a resource load that is blocked waiting for a
+  // TCP connection (or other network connection) to be established.  HTTP
+  // requests that reuse a keep-alive connection skip this state.
+  LOAD_STATE_CONNECTING,
+
+  // This state corresponds to a resource load that is blocked waiting to
+  // completely upload a request to a server.  In the case of a HTTP POST
+  // request, this state includes the period of time during which the message
+  // body is being uploaded.
+  LOAD_STATE_SENDING_REQUEST,
+
+  // This state corresponds to a resource load that is blocked waiting for the
+  // response to a network request.  In the case of a HTTP transaction, this
+  // corresponds to the period after the request is sent and before all of the
+  // response headers have been received.
+  LOAD_STATE_WAITING_FOR_RESPONSE,
+
+  // This state corresponds to a resource load that is blocked waiting for a
+  // read to complete.  In the case of a HTTP transaction, this corresponds to
+  // the period after the response headers have been received and before all of
+  // the response body has been downloaded.  (NOTE: This state only applies for
+  // an URLRequest while there is an outstanding Read operation.)
