=head1 NAME

http_config

=head1 DESCRIPTION

Example config plugin.  Gets configuration data via http requests.

=head1 CONFIG

http_config is configured at plugin loading time via the plugins
config.  Load the plugin with a list of urls like the following (on one line)
 
  http_config http://localhost/~smtpd/config/ http://www.example.com/cgi-bin/qp?config=

Looking to config "me", qpsmtpd will try loading
http://localhost/~smtpd/config/me and if failing that try
http://www.example.com/cgi-bin/qp?config=me

=head1 BUGS

http_config doesn't do any caching.  It should do some simple caching
to be used in production.
