NAME

       Bio::Root::HTTPget - module for fallback HTTP get operations when LWP:: is unavailable

SYNOPSIS

        use Bio::Root::HTTPget;
        my $web = Bio::Root::HTTPget->new();

        my $response = $web->get('http://localhost');
        $response    = $web->get('http://localhost/images');

        $response    = eval { $web->get('http://fred:secret@localhost/ladies_only/')
                            } or warn $@;

        $response    = eval { $web->get('http://jeff:secret@localhost/ladies_only/')
                            } or warn $@;

        $response    = $web->get('http://localhost/images/navauthors.gif');
        $response    = $web->get(-url=>'http://www.google.com',
                                           -proxy=>'http://www.modperl.com');

DESCRIPTION

       This is basically an last-chance module for doing network HTTP get requests in situations where more
       advanced external CPAN modules such as LWP:: are not installed.

       The particular reason this module was developed was so that the Open Bio Database Access code can
       fallback to fetching the default registry files from http://open-bio.org/registry/ without having to
       depend on external dependencies like Bundle::LWP for network HTTP access.

       The core of this module was written by Lincoln Stein. It can handle proxies and HTTP-based proxy
       authentication.
