HTTP::Server::Simple::CGI::Environment - a HTTP::Server::Simple mixin to provide the CGI protocol
DESCRIPTION
This mixin abstracts the CGI protocol out from HTTP::Server::Simple::CGI so that it's easier to provide your own CGI handlers with
HTTP::Server::Simple which don't use CGI.pm
setup_environment
"setup_environemnt" is usually called in the superclass's accept_hook
This routine in this sub-class clears the environment to the start-up state.
setup_server_url
Sets up the "SERVER_URL" environment variable
setup_environment_from_metadata
This method sets up CGI environment variables based on various meta-headers, like the protocol, remote host name, request path, etc.
See the docs in HTTP::Server::Simple for more detail.
header
"header" turns a single HTTP headers into CGI environment variables.

HTTP::Server::Simple::Authen - Authentication plugin for HTTP::Server::Simple
SYNOPSIS
package MyServer;
use base qw( HTTP::Server::Simple::Authen HTTP::Server::Simple::CGI);
use Authen::Simple::Passwd;
sub authen_handler {
Authen::Simple::Passwd->new(passwd => '/etc/passwd');
}
sub handle_request {
my($self, $cgi) = @_;
my $user = $self->authenticate or return;
...
}
MyServer->new->run();
DESCRIPTION
HTTP::Server::Simple::Authen is an HTTP::Server::Simple plugin to allow HTTP authentication. Authentication scheme is pluggable and you can
use whatever Authentication protocol that Authen::Simple supports.
You can use "authenticate" method whatever you want to authenticate the request. The method returns $username taken from the request if the
authentication is successful, and "undef" otherwise. The code in "SYNOPSIS" requires authentication for all the requests and behaves just
the same as Apache's "Require valid-user".
The following code will explain more about conditioning.
sub handle_request {
my($self, $cgi) = @_;
if ($cgi->path_info =~ m!/foo/!) {
my $user = $self->authenticate;
return unless defined($user) && length($user) == 8;
}
...
}
This means all the requests to URL "/foo/" require to be authenticated, and usernames with 8 chars long are authorized.
METHODS
Your subclass has to override following methods to implement HTTP authentication.
authen_handler
Should return a valid Authen::Simple instance to authenticate HTTP request (Required).
authen_realm
Returns a string for Authentication realm to be shown in the browser's dialog box. Defaults to 'Authorized area'.
