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.
