In commit 1795292 we updated ServeBlob() to use an io.MultiWriter to write simultaneously to the local store and the HTTP response. However, copyContent was using a type assertion to only add headers if the io.Writer was a http.ResponseWriter. Therefore, this change caused us to stop sending the expected headers (i.e. Content-Length, Etag, etc.) on the first request for a blob. Resolve the issue by explicitly passing in http.Header and setting it unconditionally. Signed-off-by: Mikel Rychliski <mikel@mikelr.com>
