Title: add missing 'content-length' header for HTTP responses.

according to the README,

Not only does the JSON file get streamed to the HTTP Response it will include an Etag, Last-Modified, Content-Length, and a Content-Type header based on the filed extension.

but only three of these headers are being sent right now; `Content-Length` is missing.
