NAME

       HTTP::CookieJar - A minimalist HTTP user agent cookie jar

VERSION

       version 0.008

SYNOPSIS

         use HTTP::CookieJar;

         my $jar = HTTP::CookieJar->new;

         # add cookie received from a request
         $jar->add( "http://www.example.com/", "CUSTOMER=WILE_E_COYOTE; Path=/; Domain=example.com" );

         # extract cookie header for a given request
         my $cookie = $jar->cookie_header( "http://www.example.com/" );

DESCRIPTION

       This module implements a minimalist HTTP user agent cookie jar in conformance with RFC
       6265 <http://tools.ietf.org/html/rfc6265>.

       Unlike the commonly used HTTP::Cookies module, this module does not require use of
       HTTP::Request and HTTP::Response objects.  An LWP-compatible adapter is available as
       HTTP::CookieJar::LWP.

CONSTRUCTORS

   new
           my $jar = HTTP::CookieJar->new;

       Return a new, empty cookie jar

METHODS

   add
           $jar->add(
               "http://www.example.com/", "lang=en-US; Path=/; Domain=example.com"
           );

       Given a request URL and a "Set-Cookie" header string, attempts to adds the cookie to the
       jar.  If the cookie is expired, instead it deletes any matching cookie from the jar.  A
       "Max-Age" attribute will be converted to an absolute "Expires" attribute.

       It will throw an exception if the request URL is missing or invalid.  Returns true if
       successful cookie processing or undef/empty-list on failure.

   clear
           $jar->clear

       Empties the cookie jar.

   cookies_for
           my @cookies = $jar->cookies_for("http://www.example.com/foo/bar");

       Given a request URL, returns a list of hash references representing cookies that should be
       sent.  The hash references are copies -- changing values will not change the cookies in
       the jar.

       Cookies set "secure" will only be returned if the request scheme is "https".  Expired
       cookies will not be returned.

       Keys of a cookie hash reference might include:

       •   name -- the name of the cookie

       •   value -- the value of the cookie

       •   domain -- the domain name to which the cookie applies

       •   path -- the path to which the cookie applies

       •   expires -- if present, when the cookie expires in epoch seconds

       •   secure -- if present, the cookie was set "Secure"

       •   httponly -- if present, the cookie was set "HttpOnly"

       •   hostonly -- if present, the cookie may only be used with the domain as a host

       •   creation_time -- epoch seconds since the cookie was first stored

       •   last_access_time -- epoch seconds since the cookie was last stored

       Keep in mind that "httponly" means it should only be used in requests and not made
       available via Javascript, etc.  This is pretty meaningless for Perl user agents.

       Generally, user agents should use the "cookie_header" method instead.

       It will throw an exception if the request URL is missing or invalid.

   cookie_header
           my $header = $jar->cookie_header("http://www.example.com/foo/bar");

       Given a request URL, returns a correctly-formatted string with all relevant cookies for
       the request.  This string is ready to be used in a "Cookie" header in an HTTP request.
       E.g.:

           SID=31d4d96e407aad42; lang=en-US

       It follows the same exclusion rules as "cookies_for".

       If the request is invalid or no cookies apply, it will return an empty string.

   dump_cookies
           my @list = $jar->dump_cookies;
           my @list = $jar->dump_cookies( { persistent => 1 } );

       Returns a list of raw cookies in string form.  The strings resemble what would be received
       from "Set-Cookie" headers, but with additional internal fields.  The list is only intended
       for use with "load_cookies" to allow cookie jar persistence.

       If a hash reference with a true "persistent" key is given as an argument, cookies without
       an "Expires" time (i.e. "session cookies") will be omitted.

       Here is a trivial example of saving a cookie jar file with Path::Tiny:

           path("jar.txt")->spew( join "\n", $jar->dump_cookies );

   load_cookies
           $jar->load_cookies( @cookies );

       Given a list of cookie strings from "dump_cookies", it adds them to the cookie jar.
       Cookies added in this way will supersede any existing cookies with similar domain, path
       and name.

       It returns the jar object for convenience when loading a new object:

           my $jar = HTTP::CookieJar->new->load_cookies( @cookies );

       Here is a trivial example of loading a cookie jar file with Path::Tiny:

           my $jar = HTTP::CookieJar->new->load_cookies(
               path("jar.txt")->lines
           );

LIMITATIONS AND CAVEATS

   RFC 6265 vs prior standards
       This modules adheres as closely as possible to the user-agent rules of RFC 6265.
       Therefore, it does not handle nor generate "Set-Cookie2" and "Cookie2" headers, implement
       ".local" suffixes, or do path/domain matching in accord with prior RFC's.

   Internationalized domain names
       Internationalized domain names given in requests must be properly encoded in ASCII form.

   Public suffixes
       If Mozilla::PublicSuffix is installed, cookie domains will be checked against the public
       suffix list.  Public suffix cookies are only allowed as host-only cookies.

   Third-party cookies
       According to RFC 6265, a cookie may be accepted only if has no "Domain" attribute (in
       which case it is "host-only") or if the "Domain" attribute is a suffix of the request URL.
       This effectively prohibits Site A from setting a cookie for unrelated Site B, which is one
       potential third-party cookie vector.
