The Blacklist plugin must be called back whenever its
configuration is changed by an administrator. To get the interface working, you need an interface
program (such as a CGI form) to display an interface and obtain
configuration information and a text file that the CGI program edits
and the Blacklist plugin reads. The callback to the plugin is
established in INKPluginInit by:
INKMgmtUpdateRegister (contp, "Dianes Blacklist Plugin", "blacklist.cgi");
Above, contp is the plugin’s static parent
continuation, Dianes Blacklist Plugin is the name of the plugin as
specified by the CGI form’s INK_PLUGIN_NAME variable, and blacklist.cgi is the path to the plugin’s
interface program (relative to the Traffic Server plugins directory).
