=head1 SYNOPSIS


=for example begin

  use APR::Request::Cookie;

  # fetch inbound cookie
  $jar = $req->jar;
  $cookie1 = $jar->get("cookie1");

  # generate new cookie
  $cookie = APR::Request::Cookie->new($req->pool,
                                      name => "foo",
                                     value => "bar",
                                    domain => "capricorn.com");
  print "$cookie"; # prints "bar"

  $cookie->domain("example.com"); # change domains
  $cookie->version(1); # upgrade it to conform with RFC 2109/2965.

  # send a response header
  print sprintf "Set-Cookie: %s\n", $cookie->as_string;

=for example end

=for example_testing
  ok "$cookie1" eq "apache1";
  ok $jar->isa("APR::Request::Cookie::Table");
  is $_STDOUT_ , qq[barSet-Cookie: foo=bar; Version=1; domain="example.com"\n];




=head1 DESCRIPTION

The APR::Request::Cookie module provides base methods
for interfacing with libapreq2's cookie API.  It also provides
a few utility functions and constants.

This manpage documents version 2.08
of the APR::Request::Cookie package.




=head1 OVERLOADS

APR::Request::Cookie




=head2 ""

    "$cookie"

The double-quote interpolation operator maps to
C<< APR::Request::Cookie::value() >>.

=for example begin

    ok "$cookie" eq $cookie->value;

=for example end

=for example_testing
    1;


=head1 METHODS

APR::Request::Cookie




=head2 new

    APR::Request::Cookie->new($pool,
                               name => $name,
                              value => $value,
                              %args)


Creates a new cookie.  Here C<< $pool >> is an APR::Pool object,
and C<< $name >> is the cookie's name. The C<< $value >> is transformed
into the cookie's raw value through the class' C<< freeze() >> method.
The remaining arguments are optional:

=over 4

=item -secure

=item -version

=item -path

=item -domain

=item -port

=item -expires

=item -comment

=item -commentURL

=back

For details on these arguments, please consult
the corresponding method's documentation.




=head2 freeze

    APR::Request::Cookie->freeze($value)

Class method representing the default serializer;
here it returns $value unmodified.

=for example begin

    ok "foo" eq APR::Request::Cookie->freeze("foo");

=for example end

=for example_testing
    1;




=head2 thaw

    $cookie->thaw()

Reverses C<< freeze() >>; here it simply returns 
$cookie->value since freeze() is a noop.

=for example begin

    ok $cookie->thaw eq $cookie->value;

=for example end

=for example_testing
    1;




=head2 name

    $cookie->name()

Fetch the cookie's name.  This attribute
cannot be modified and is never serialized;
ie freeze() and thaw() do not act on the
cookie's name.

=for example begin

=for example end

=for example_testing
    is $cookie->name, "foo", "name";




=head2 value

    $cookie->value()

Fetch the cookie's raw (frozen) value.
This attribute cannot be modified.

=for example begin

=for example end

=for example_testing
    is $cookie->value, "bar", "value";




=head2 secure

    $cookie->secure()
    $cookie->secure($set)


Get/set the cookie's secure flag.

=for example begin

    $cookie->secure(1);

    is $cookie->secure, 0, "secure";




=head2 version

    $cookie->version()
    $cookie->version($set)

Get/set the cookie's version number.
Version 0 cookies conform to the Netscape
spec; Version 1 cookies conform to either
RFC 2109 or RFC 2965.

=for example begin

    $version = $cookie->version;
    $cookie->version(1);
    ok $cookie->version == 1;

=for example end

=for example_testing
    $cookie->version($version);
    is $cookie->version, $version, "version";




=head2 path

    $cookie->path()
    $cookie->path($set)

Get/set the cookie's path string.

=for example begin

    $path = $cookie->path;
    $cookie->path("/1/2/3/4");

=for example end

=for example_testing
    $cookie->path($path);
    is $cookie->path, $path, "path";




=head2 domain

    $cookie->domain()
    $cookie->domain($set)

    is $cookie->is_tainted, $tainted, "tainted";


=head2 make

    APR::Request::Cookie->make($pool, $name, $value)

Fast XS cookie constructor invoked by C<< new() >>.
The cookie's raw name & value are taken directly from the
passed in arguments; no freezing/encoding is done on the $value.




=head2 as_string

    $cookie->as_string()


String representation of the cookie, suitable for inclusion
