So the proxy is definitely broken.\nSame happens with a HEAD request:\n\ncurl -I https://databox.me/,proxy?uri=http%3A%2F%2Flocalhost%3A3080%2Ftimbl%2FPublic%2FPublicTypeIndex.ttl\ncurl: (52) Empty reply from server\n\nThat said, the original resource being proxied is a bit strange.\nIt has a content-length of 2 in a HEAD:\n``\n $ curl -I http://localhost:3080/timbl/Public/PublicTypeIndex.ttl\nHTTP/1.1 200 OK\nX-Powered-By: Express\nLink: \u003cPublicTypeIndex.ttl.acl\u003e; rel=\"acl\", \u003cPublicTypeIndex.ttl.meta\u003e; rel=\"describedBy\", \u003chttp://www.w3.org/ns/ldp#Resource\u003e; rel=\"type\"\nVary: Origin\nAccess-Control-Allow-Credentials: true\nAccess-Control-Expose-Headers: User, Location, Link, Vary, Last-Modified, Content-Length\nMS-Author-Via: SPARQL\nUpdates-Via: http://localhost:3080\nContent-Type: text/plain; charset=utf-8\nContent-Length: 2\nETag: W/\"2-4KoCHiHd29bYzs7HHpz1ZA\"\nset-cookie: connect.sid=s%3A1M4dZlcCPpfdrXlzHj7qdzJGIQXwDqTG.j2qJWrO1B0OKg7MJ%2FEhnxv0xgcJsR802ZQ0XC8RyRL4; Path=/; HttpOnly\nDate: Wed, 17 Feb 2016 11:30:05 GMT\nConnection: keep-alive\n\ntimbl 06:35\nwell that was my localhost copy.

Is that an excuse for the proxy to disconnect? But it should sent the content-length, even if it uses streaming internally.\nSo this looks like three bugs\n\n- The bad content-length of 2 on a HEAD\n- the missing content-length (I mean) on the GET (from ldnode)\n- in gold, the bad reaction in closing down the client connection, whcih should not happen even if no content-length\n```\n","author":{"url":"https://github.com/timbl","@type":"Person","name":"timbl"},"datePublished":"2016-02-17T11:48:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/250/node-solid-server/issues/250"}
