Sample Source Code
******************

.. _denylist-1.c:

denylist_1.c
-------------

The sample denylisting plugin included in the Traffic Server SDK is
``denylist_1.c``. This plugin checks every incoming HTTP client request
against a list of web sites. If the client requests a
listed site, then the plugin returns an ``Access forbidden``
message to the client.

This plugin illustrates:

-  An HTTP transaction extension

-  How to examine HTTP request headers

-  How to use the logging interface

-  How to use the plugin configuration management interface
