#------------------------------------
# To go from 100 nanosecond intervals to seconds since 00:00 Jan 01 1970:
#
# 1. Adjust 100 nanosecond intervals to Jan 01 1970 base
# 2. Divide by 10 to get to microseconds (1/millionth second)
# 3. Divide by 1000000 (10 ^ 6) to get to seconds
#
# We can combine Step 2 & 3 into one divide.
#
# After much trial and error, I came up with the following code which
# avoids using Math::BigInt or floating pt, but still gives correct answers
# If the filetime is before the epoch, return 0

=head1 NAME
HTTP::Cookies::Microsoft - access to Microsoft cookies files
=head1 SYNOPSIS
use LWP;
use HTTP::Cookies::Microsoft;
use Win32::TieRegistry(Delimiter => "/");
my $cookies_dir = $Registry->
{"CUser/Software/Microsoft/Windows/CurrentVersion/Explorer/Shell Folders/Cookies"};
$cookie_jar = HTTP::Cookies::Microsoft->new(
file => "$cookies_dir\\index.dat",
'delayload' => 1,
);
my $browser = LWP::UserAgent->new;
$browser->cookie_jar( $cookie_jar );
=head1 DESCRIPTION
This is a subclass of C<HTTP::Cookies> which
loads Microsoft Internet Explorer 5.x and 6.x for Windows (MSIE)
cookie files.
See the documentation for L<HTTP::Cookies>.
=head1 METHODS
The following methods are provided:
=over 4
=item $cookie_jar = HTTP::Cookies::Microsoft->new;
The constructor takes hash style parameters. In addition
to the regular HTTP::Cookies parameters, HTTP::Cookies::Microsoft
recognizes the following:
delayload: delay loading of cookie data until a request
is actually made. This results in faster
runtime unless you use most of the cookies
since only the domain's cookie data
is loaded on demand.
=back
=head1 CAVEATS
Please note that the code DOESN'T support saving to the MSIE
cookie file format.
