API

createHeaderParser(callback)

Returns a Function that should be called with a stream.Duplex (e.g. net.Socket) that you want to parse.

callback(headers, stream)

Type: Function

The callback will be called after HTTP headers are parsed. headers is an object with the actual headers (see http-headers for details). stream is a stream.Duplex and it's basically a wrapper around the original stream. Note that the stream will output all the data from the original stream, including the headers.

Dependencies

• http-headers
