middleware to compress response body with gzip or deflate
Plack::Middleware::Deflater is a middleware to encode your response body in gzip or deflate, based on the Accept-Encoding HTTP request header. While saving a little bandwidth it will increase the Plack server load, so ideally you should handle this on the frontend reverse proxy servers. . This middleware removes Content-Length and streams encoded content, which means the server should support HTTP/1.1 chunked response or downgrade to HTTP/1.0 and close the connection.
