response.setHeader (iojs 1.0.1) != response.setHeader (node 11.14)

[stephen-bartell]

when running on node 11.14, value: undefined is allowed. not so in io 1.0.1.

response.setHeader('location', undefined)

throws:

Error: "name" and "value" are required for setHeader().

That's nodejs/node-v0.x-archive@979d0ca8 but that change hasn't made its way into a release yet. I've been given to understand that v0.11.15 will be released "any day now."
