# PlugResponseHeader [![Hex.pm Version](http://img.shields.io/hexpm/v/plug_response_header.svg)](https://hex.pm/packages/plug_response_header)


This plug allows manipulation of HTTP response headers:

* Deleting one or more HTTP response headers.
* Setting one or more HTTP response headers.
* Setting the HTTP "Server" response header.

This plug supports the following options. At least one option must be specified.

* `set`: a list of key/value pairs for headers to be set.
