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
