new

    Apache2::Cookie::Jar->new($env)

Class method that retrieves the parsed cookie jar from the current environment.

cookies

    $jar->cookies()
    $jar->cookies($key)

Retrieve cookies named $key with from the jar object. In scalar context the first such cookie is returned, and in list context the full list of such cookies are returned.

If the $key argument is omitted, "scalar $jar->cookies()" will return an APR::Request::Cookie::Table object containing all the cookies in the jar. Modifications to the this object will affect the jar's internal cookies table in "apreq_jar_t", so their impact will be noticed by all libapreq2 applications during this request.

In list context "$jar->cookies()" returns the list of names for all the cookies in the jar. The order corresponds to the order in which the cookies appeared in the incoming "Cookie" header.

This method will throw an "APR::Request::Error" object into $@ if the returned value(s) could be unreliable. In particular, note that "scalar $jar->cookies("foo")" will not croak if it can locate the a "foo" cookie within the jar's parsed cookie table, even if the cookie parser has failed (the cookies are parsed in the same order as they appeared in the "Cookie" header). In all other circumstances "cookies" will croak if the parser failed to successfully parse the "Cookie" header.

    $c = Apache2::Cookie->new($r, name => "foo", value => 3);
    $j->cookies->add($c);
    $cookie = $j->cookies("foo");  # first foo cookie
    @cookies = $j->cookies("foo"); # all foo cookies
    @names = $j->cookies();        # all cookie names

status

    $jar->status()

Get the APR status code of the cookie parser: APR_SUCCESS on success, error otherwise.

new

    Apache2::Cookie->new($env, %args)

Just like CGI::Cookie::new, but requires an additional environment argument:

    $cookie = Apache2::Cookie->new($r,
                             -name    =>  'foo',
                             -value   =>  'bar',
                             -expires =>  '+3M',
                             -domain  =>  '.capricorn.com',
                             -path    =>  '/cgi-bin/database',
                             -secure  =>  1
                            );

The "-value" argument may be either an arrayref, a hashref, or a string. "Apache2::Cookie::freeze" encodes this argument into the cookie's raw value.

freeze

    Apache2::Cookie->freeze($value)

Helper function (for "new") that serializes a new cookie's value in a manner compatible with CGI::Cookie (and Apache2::Cookie 1.X). This class method accepts an arrayref, hashref, or normal perl string in $value.

    $value = Apache2::Cookie->freeze(["2+2", "=4"]);

thaw

    Apache2::Cookie->thaw($value)
    $cookie->thaw()

This is the helper method (for "value") responsible for decoding the raw value of a cookie. An optional argument $value may be used in place of the cookie's raw value. This method can also decode cookie values created using CGI::Cookie or Apache2::Cookie 1.X.

    print $cookie->thaw;                    # prints "bar"
    @values = Apache2::Cookie->thaw($value); # ( "2+2", "=4" )

as_string

    $cookie->as_string()

Format the cookie object as a string. The quote-operator for Apache2::Cookie is overloaded to run this method whenever a cookie appears in quotes.

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

name

    $cookie->name()

Get the name of the cookie.

value

    $cookie->value()

Get the (unswizzled) value of the cookie:

    my $value = $cookie->value;
    my @values = $cookie->value;

Note: if the cookie's value was created using a "freeze" method, one way to reconstitute the object is by subclassing Apache2::Cookie with a package that provides the associated "thaw" sub:

    {
        package My::COOKIE;
        @ISA = 'Apache2::Cookie';
        sub thaw { my $val = shift->raw_value; $val =~ tr/a-z/A-Z/; $val }
    }
    bless $cookie, "My::COOKIE";
    ok $cookie->value eq "BAR";

raw_value

    $cookie->raw_value()

Gets the raw (opaque) value string as it appears in the incoming "Cookie" header.

    ok $cookie->raw_value eq "bar";

bake

    $cookie->bake($r)

Adds a Set-Cookie header to the outgoing headers table.

bake2

    $cookie->bake2($r)

Adds a Set-Cookie2 header to the outgoing headers table.

domain

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

Get or set the domain for the cookie:

    $domain = $cookie->domain;
    $cookie->domain(".cp.net");

path

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

Get or set the path for the cookie:

    $path = $cookie->path;
    $cookie->path("/");

version

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

Get or set the cookie version for this cookie. Netscape spec cookies have version = 0; RFC-compliant cookies have version = 1.

    ok $cookie->version == 0;
    $cookie->version(1);
    ok $cookie->version == 1;

expires

    $cookie->expires()
    $cookie->expires($set)

Get or set the future expire time for the cookie. When assigning, the new value ($set) should match /^\+?(\d+)([YMDhms]?)$/ $2 qualifies the number in $1 as representing "Y"ears, "M"onths, "D"ays, "h"ours, "m"inutes, or "s"econds (if the qualifier is omitted, the number is interpreted as representing seconds). As a special case, $set = "now" is equivalent to $set = "0".

    my $expires = $cookie->expires;
    $cookie->expires("+3h"); # cookie is set to expire in 3 hours

secure

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

Get or set the secure flag for the cookie:

    $cookie->secure(1);
    $is_secure = $cookie->secure;
    $cookie->secure(0);

httponly

    $cookie->httponly()
    $cookie->httponly($set)

Get or set the HttpOnly flag for the cookie:

    $cookie->httponly(1);
    $is_HttpOnly = $cookie->httponly;
    $cookie->httponly(0);

comment

    $cookie->comment()
    $cookie->comment($set)

Get or set the comment field of an RFC (Version > 0) cookie.

    $cookie->comment("Never eat yellow snow");
    print $cookie->comment;

commentURL

    $cookie->commentURL()
    $cookie->commentURL($set)

Get or set the commentURL field of an RFC (Version > 0) cookie.

    $cookie->commentURL("http://localhost/cookie.policy");
    print $cookie->commentURL;

fetch

    Apache2::Cookie->fetch($r)

Fetch and parse the incoming Cookie header:

    my $cookies = Apache2::Cookie->fetch($r); # APR::Request::Cookie::Table ref
    It should be noted, that with perl 5.8+ Iterator magic, table is able
    to handle multiple cookies of the same name.
    my %cookies = Apache2::Cookie->fetch($r);
