Node/Nginx "no reply" from malformed uris

[Trevor]

Hello,

I'm using Node backed by nginx with a simple `proxy_pass`. I've encountered errors in my nginx logs regarding malformed uris.

If I issue a request that looks like curl  "$(printf 'http://myserver/\x02')" then the request is dropped by node. This leaves nginx without a response and sends back a 502 to the client. The real problem occurs when valid request comes at the same time (or near). The dropped, malformed requests makes nginx also drop the other requests, valid or not.

I believe this is related to nodejs dropping the connection: https://github.com/joyent/node/issues/6756

1 of the solutions recommended by some posts is to normalize the requests by adding a `/` to the upstream server, but that creates problems for routes on the node server.

Ideally, the malformed request should return a 400 by nginx.

Has anyone else encountered and solved this problem?

Any help is appreciated. Thanks!
