conf_remap Plugin
=================

The `conf_remap` plugin allows you to override configuration
directives dependent on actual remapping rules. The plugin is built
and installed as part of the normal Apache Traffic Server installation
process.

The `conf_remap` plugin accepts configuration directives in the
arguments list or in a separate configuration file. In both cases,
only string and integer directives are supported.

When using a separate configuration file, the standard
:file:`records.config` syntax is used, for example::

    map http://cdn.example.com/ http://some-server.example.com \
      @plugin=conf_remap.so @pparam=/etc/trafficserver/cdn.conf

where `cdn.conf` contains::

    CONFIG proxy.config.url_remap.pristine_host_hdr INT 1

When using inline arguments, the `conf_remap` plugin accepts a
``key=value`` syntax, where the ``KEY`` is the name of the configuration
directive and ``VALUE`` is the desired value, for example::

    map http://cdn.example.com/ http://some-server.example.com \
      @plugin=conf_remap.so @pparam=proxy.config.url_remap.pristine_host_hdr=1

Doing this, you will override your global default configuration on
a per mapping rule. For more details on the APIs, functionality, and a
complete list of all overridable configurations, see :ref:`ts-overridable-config`.
