The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields....\n\nlightnode currently uses the chunked encoding header for all responses, including 304s.  This results in a \"0\\r\\n\" following the message headers.\n\nThe following change to move the chunked header to the else clause resolves the issue for me.\n\n``` javascript\n\n                       //REMOVED headers['transfer-encoding'] = 'chunked'\n                        headers['server'] = 'lightnode'\n\n                        if (Date.parse(file.header.mtime) \u003c= Date.parse(req.headers['if-modified-since'])) {\n                                resp.writeHead(304, headers)\n                                resp.end()\n                                return\n                        }\n                        else {\n                                headers['transfer-encoding'] = 'chunked' // ADDED\n```\n","author":{"url":"https://github.com/eoinsha","@type":"Person","name":"eoinsha"},"datePublished":"2012-06-27T10:40:21.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/13/lightnode/issues/13"}
