Please update the comment.

Done.

-  if (factory.type() != Resource::MainResource)
+  if (factory.type() != Resource::MainResource &&
+      request.options().dataBufferingPolicy == BufferData)

optional: |request.options().dataBufferingPolicy != DoNotBufferData| might be
easier to read ("Add to memory cache, unless MainResource or DoNotBufferData").

[yhirano, 2016/11/16 07:21:49]

Done.

     memoryCache()->add(resource);
   return resource;
 }
