Apache2::Cookie(3) HTTP Cookies Class

Other Alias



use Apache2::Cookie;
$j = Apache2::Cookie::Jar->new($r);
$c_in = $j->cookies("foo"); # get cookie from request headers
$c_out = Apache2::Cookie->new($r,
-name => "mycookie",
-value => $c_in->name );
$c_out->path("/bar"); # set path to "/bar"
$c_out->bake; # send cookie in response headers


The Apache2::Cookie module is based on the original 1.X versions, which mimic the CGI::Cookie API. The current version of this module includes several packages and methods which are patterned after Apache2::Request, yet remain largely backwards-compatible with the original 1.X API (see the ``PORTING from 1.X'' section below for known issues).

This manpage documents the Apache2::Cookie and Apache2::Cookie::Jar packages.


This class collects Apache2::Cookie objects into a lookup table. It plays the same role for accessing the incoming cookies as Apache2::Request does for accessing the incoming params and file uploads.



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



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);
    $cookie = $j->cookies("foo");  # first foo cookie
    @cookies = $j->cookies("foo"); # all foo cookies
    @names = $j->cookies();        # all cookie names



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



    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.



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"]);



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" )



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;



Get the name of the cookie.



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";



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

    ok $cookie->raw_value eq "bar";



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



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



Get or set the domain for the cookie:

    $domain = $cookie->domain;



Get or set the path for the cookie:

    $path = $cookie->path;



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;
    ok $cookie->version == 1;



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



Get or set the secure flag for the cookie:

    $is_secure = $cookie->secure;



Get or set the HttpOnly flag for the cookie:

    $is_HttpOnly = $cookie->httponly;



Get or set the HttpOnly flag for the cookie:

    $is_HttpOnly = $cookie->httponly;



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

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



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

    print $cookie->commentURL;



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);

PORTING from 1.X

Changes to the 1.X API:
  • "Apache2::Cookie::fetch" now expects an $r object as (second)
            argument, although this isn't necessary in mod_perl 2 if
            "Apache2::RequestUtil" is loaded and 'PerlOptions +GlobalRequest'
            is in effect.
  • "Apache2::Cookie::parse" is gone.
  • "Apache2::Cookie::new" no longer encodes the supplied cookie name.
  • "Apache2::Cookie::new()" returns undef if -value is not specified
            or -value => undef.
  • "name()" and "value()" no longer accept a ``set'' argument. In other words,
            neither a cookie's name, nor its value, may be modified.  A new cookie
            should be made instead.
