Exception after 1.15.1

[ducklord]

Hey

We are getting this exception The header content contains invalid characters after the update of 1.15.1. The reason is that union's response-stream does not implement the interface you describe in the 1.15.1 patch.

TypeError: The header content contains invalid characters
    at ServerResponse.OutgoingMessage.setHeader (_http_outgoing.js:351:13)
    at ResponseStream.writeHead (node_modules/union/lib/response-stream.js:75:21)
    at Array.writeStatusCode (node_modules/http-proxy/lib/http-proxy/passes/web-outgoing.js:113:11)
    at ClientRequest.<anonymous> (node_modules/http-proxy/lib/http-proxy/passes/web-incoming.js:157:20)

Not sure if you are willing to fix this, since this is basically unions fault. But the error is first exposed in your 1.15.1.

Best regards
Anders

I'm seeing this in Chrome 52 running it as part of Express middleware. It happens in 1.15.1 and 1.15.2, but it is fine in 1.13.3.

@ducklord the fix should be in union. @reykjavikingur could you post some code, a stacktrace and the version of express this is associated with?

This should be fixed with latest union which would be installed with latest http-server. @reykjavikingur would love to see a test for your failure case added to this project. It doesn't seem clear to me why this would be happening with standard express
