(It's a little weird to be storing two copies of the same information on a
WebURLResponse, but I'll defer to part 1's review there.)

   response->setMIMEType(WebString::fromUTF8(info.mime_type));
   response->setTextEncodingName(WebString::fromUTF8(info.charset));
   response->setExpectedContentLength(info.content_length);
