NAME

POE::Declare::HTTP::Online - Does your POE process have access to the web

SYNOPSIS

    my $online = POE::Declare::HTTP::Online->new(
        Timeout      => 10,
        OnlineEvent  => \&handle_online,
        OfflineEvent => \&handle_offline,
        ErrorEvent   => \&handle_unknown,
    );
    
    $online->run;

DESCRIPTION

This is a port of LWP::Online to POE::Declare. It behaves similarly to the original, except that it does not depend on LWP and can execute the HTTP probes in parallel.

new

    my $online = POE::Declare::HTTP::Online->new(
        Timeout      => 10,
        OnlineEvent  => \&handle_online,
        OfflineEvent => \&handle_offline,
        ErrorEvent   => \&handle_unknown,
    );

The new constructor sets up a reusable HTTP online status checker that can be run as often as needed.

Unless actively in use, the online detection object will not consume a POE session.

run

The run method starts the online detection process, spawning the POE session and initiating HTTP Test to each of the test URLs in parallel.

Once a determination has been made as to our online state (positive, negative or unknown) and the reporting event has been fired, the session will be terminated immediately.
