Setting header again appends to header, not replaces

[dalisoft]

Hi.

Related issue: #150

As title says, when again setting res.setHeader(key, value) appends to same header, not replaces.

It is bug? Or am i doing something wrong?

There is no res.setHeader, you only have res.writeHeader

Yep, setHeader in my app :)
I forgot to say, yes, same bug applies to writeStatus too
