from http.server import HTTPServer, BaseHTTPRequestHandler
import socketserver

PORT = 8080

Handler = http.server.SimpleHTTPRequestHandler

Handler.extensions_map={
        '.manifest': 'text/cache-manifest',
	'.html': 'text/html',

	'': 'application/octet-stream', # Default
    }

httpd = socketserver.TCPServer(("", PORT), Handler)

print("serving at port", PORT)
httpd.serve_forever()
