Set Headers
===========

This feature lets you specify a set of headers to be added to requests or
responses, based on a filter pattern. You can specify these either on the
command-line, or through an interactive editor in mitmproxy.

Example: Set the **Host** header to "example.com" for all requests.

.. code-block:: none

    mitmdump -R http://example.com --setheader :~q:Host:example.com
