=head1 NAME
Business::OnlinePayment::HTTPS - Base class for HTTPS payment APIs
=head1 SYNOPSIS
package Business::OnlinePayment::MyProcessor
@ISA = qw( Business::OnlinePayment::HTTPS );
sub submit {
my $self = shift;
#...
# pass a list (order is preserved, if your gateway needs that)
($page, $response, %reply_headers)
= $self->https_get( field => 'value', ... );
#or a hashref
my %hash = ( field => 'value', ... );
($page, $response_code, %reply_headers)
= $self->https_get( $hashref );
#...
}
=head1 DESCRIPTION
This is a base class for HTTPS based gateways, providing useful code for
implementors of HTTPS payment APIs.
It depends on Net::SSLeay _or_ ( Crypt::SSLeay and LWP::UserAgent ).
=head1 METHODS
=over 4
=item https_get HASHREF | FIELD => VALUE, ...
Accepts parameters as either a hashref or a list of fields and values. In the
latter case, ordering is preserved (see L<Tie::IxHash> to do so when passing a
hashref).
Returns a list consisting of the page content as a string, the HTTP response
code, and a list of key/value pairs representing the HTTP response headers.

my $self = shift;
#accept a hashref or a list (keep it ordered)
