678 | =head1 NAME |
679 | |
7048c24e |
680 | Catalyst::Plugin::Session - Generic Session plugin - ties together server side storage and client side state required to maintain session data. |
9e447f9d |
681 | |
682 | =head1 SYNOPSIS |
683 | |
8f0b4c16 |
684 | # To get sessions to "just work", all you need to do is use these plugins: |
685 | |
686 | use Catalyst qw/ |
687 | Session |
688 | Session::Store::FastMmap |
689 | Session::State::Cookie |
690 | /; |
691 | |
7048c24e |
692 | # you can replace Store::FastMmap with Store::File - both have sensible |
693 | # default configurations (see their docs for details) |
8f0b4c16 |
694 | |
7048c24e |
695 | # more complicated backends are available for other scenarios (DBI storage, |
696 | # etc) |
8f0b4c16 |
697 | |
698 | |
699 | # after you've loaded the plugins you can save session data |
700 | # For example, if you are writing a shopping cart, it could be implemented |
701 | # like this: |
9e447f9d |

703 | sub add_item : Local { |
704 | my ( $self, $c ) = @_; |
705 | |
706 | my $item_id = $c->req->param("item"); |
707 | |
8f0b4c16 |
708 | # $c->session is a hash ref, a bit like $c->stash |
709 | # the difference is that it' preserved across requests |
229a5b53 |
710 | |
711 | push @{ $c->session->{items} }, $item_id; |
712 | |
713 | $c->forward("MyView"); |
714 | } |
715 | |
716 | sub display_items : Local { |
717 | my ( $self, $c ) = @_; |
718 | |
719 | # values in $c->session are restored |
720 | $c->stash->{items_to_display} = |
8f0b4c16 |
721 | [ map { MyModel->retrieve($_) } @{ $c->session->{items} } ]; |

726 | =head1 DESCRIPTION |
727 | |
728 | The Session plugin is the base of two related parts of functionality required |
729 | for session management in web applications. |
730 | |
731 | The first part, the State, is getting the browser to repeat back a session key, |
732 | so that the web application can identify the client and logically string |
733 | several requests together into a session. |
734 | |
735 | The second part, the Store, deals with the actual storage of information about |
736 | the client. This data is stored so that the it may be revived for every request |
737 | made by the same client. |
738 | |
739 | This plugin links the two pieces together. |

741 | =head1 RECOMENDED BACKENDS |
8f0b4c16 |
742 | |
743 | =over 4 |
744 | |
745 | =item Session::State::Cookie |
746 | |
747 | The only really sane way to do state is using cookies. |
748 | |
749 | =item Session::Store::File |
750 | |
751 | A portable backend, based on Cache::File. |
752 | |
753 | =item Session::Store::FastMmap |
754 | |
755 | A fast and flexible backend, based on Cache::FastMmap. |

759 | =head1 METHODS |
760 | |
761 | =over 4 |
762 | |
763 | =item sessionid |
764 | |
765 | An accessor for the session ID value. |
766 | |
767 | =item session |
768 | |
769 | Returns a hash reference that might contain unserialized values from previous |
770 | requests in the same session, and whose modified value will be saved for future |
771 | requests. |
772 | |
773 | This method will automatically create a new session and session ID if none |
774 | exists. |
775 | |
a491a59b |
776 | You can also set session keys by passing a list of key/value pairs or a |
777 | hashref. |
778 | |
779 | $c->session->{foo} = "bar"; # This works. |
780 | $c->session(one => 1, two => 2); # And this. |
781 | $c->session({ answer => 42 }); # And this. |
782 | |
ab634fee |
783 | =item session_expires |
784 | |
ab634fee |
785 | This method returns the time when the current session will expire, or 0 if |
786 | there is no current session. If there is a session and it already expired, it |
787 | will delete the session and return 0 as well. |
788 | |
07e714d2 |
789 | =item flash |
790 | |
791 | This is like Ruby on Rails' flash data structure. Think of it as a stash that |
44ab6d1c |
792 | lasts for longer than one request, letting you redirect instead of forward. |
793 | |
794 | The flash data will be cleaned up only on requests on which actually use |
795 | $c->flash (thus allowing multiple redirections), and the policy is to delete |
bf6bd311 |
796 | all the keys which haven't changed since the flash data was loaded at the end |
797 | of every request. |
07e714d2 |
798 | |
ad3142b4 |
799 | Note that use of the flash is an easy way to get data across requests, but |
800 | it's also strongly disrecommended, due it it being inherently plagued with |
801 | race conditions. This means that it's unlikely to work well if your |
802 | users have multiple tabs open at once, or if your site does a lot of AJAX |
803 | requests. |
804 | |
805 | L<Catalyst::Plugin::StatusMessage> is the recommended alternative solution, |
806 | as this doesn't suffer from these issues. |

832 | |
49727697 |
833 | =item clear_flash |
834 | |
835 | Zap all the keys in the flash regardless of their current state. |
836 | |
bf6bd311 |
837 | =item keep_flash @keys |
838 | |
1961343c |
839 | If you want to keep a flash key for the next request too, even if it hasn't |
bf6bd311 |
840 | changed, call C<keep_flash> and pass in the keys as arguments. |
841 | |
fffeb18f |
842 | =item delete_session REASON |
843 | |
844 | This method is used to invalidate a session. It takes an optional parameter |
845 | which will be saved in C<session_delete_reason> if provided. |
846 | |
eb250519 |
847 | NOTE: This method will B<also> delete your flash data. |
848 | |
9e447f9d |
849 | =item session_delete_reason |
850 | |
851 | This accessor contains a string with the reason a session was deleted. Possible |
852 | values include: |
853 | |
854 | =over 4 |
855 | |
856 | =item * |
857 | |
858 | C<address mismatch> |
859 | |

b7acf64e |
866 | =item session_expire_key $key, $ttl |
867 | |
868 | Mark a key to expire at a certain time (only useful when shorter than the |
869 | expiry time for the whole session). |
870 | |
871 | For example: |
872 | |
32f97098 |
873 | __PACKAGE__->config('Plugin::Session' => { expires => 10000000000 }); # "forever" |
2110d078 |
874 | (NB If this number is too large, Y2K38 breakage could result.) |
b7acf64e |
875 | |
876 | # later |
877 | |
878 | $c->session_expire_key( __user => 3600 ); |
879 | |
880 | Will make the session data survive, but the user will still be logged out after |
881 | an hour. |
882 | |
883 | Note that these values are not auto extended. |
884 | |
0ade68bd |
885 | =item change_session_id |
886 | |
887 | By calling this method you can force a session id change while keeping all |
888 | session data. This method might come handy when you are paranoid about some |
889 | advanced variations of session fixation attack. |
890 | |
891 | If you want to prevent this session fixation scenario: |
892 | |
893 | 0) let us have WebApp with anonymous and authenticated parts |
af1e4bc8 |
894 | 1) a hacker goes to vulnerable WebApp and gets a real sessionid, |
0ade68bd |
895 | just by browsing anonymous part of WebApp |
896 | 2) the hacker inserts (somehow) this values into a cookie in victim's browser |
897 | 3) after the victim logs into WebApp the hacker can enter his/her session |
898 | |
899 | you should call change_session_id in your login controller like this: |
900 | |
901 | if ($c->authenticate( { username => $user, password => $pass } )) { |
902 | # login OK |
903 | $c->change_session_id; |
904 | ... |
905 | } else { |
906 | # login FAILED |
907 | ... |
908 | } |
909 | |
601be17a |
910 | =item change_session_expires $expires |
911 | |
912 | You can change the session expiration time for this session; |
913 | |
914 | $c->change_session_expires( 4000 ); |
915 | |
fa022110 |
916 | Note that this only works to set the session longer than the config setting. |

924 | =item setup |
925 | |
926 | This method is extended to also make calls to |
927 | C<check_session_plugin_requirements> and C<setup_session>. |
928 | |
929 | =item check_session_plugin_requirements |
930 | |
931 | This method ensures that a State and a Store plugin are also in use by the |
932 | application. |
933 | |
934 | =item setup_session |
935 | |
064c3709 |
936 | This method populates C<< $c->config('Plugin::Session') >> with the default values |
9e447f9d |
937 | listed in L</CONFIGURATION>. |
938 | |

941 | This method is extended. |

942 | |
bfa4f9cc |
943 | Its only effect is if the (off by default) C<flash_to_stash> configuration |
68fd02ae |
944 | parameter is on - then it will copy the contents of the flash to the stash at |
945 | prepare time. |

949 | This method is extended and will extend the expiry time before sending |
950 | the response. |
951 | |
92eaec32 |
952 | =item finalize_body |
d3c97126 |
953 | |
92eaec32 |
954 | This method is extended and will call finalize_session before the other |
955 | finalize_body methods run. Here we persist the session data if a session exists. |
9e447f9d |
956 | |
9e447f9d |
957 | =item initialize_session_data |
958 | |
959 | This method will initialize the internal structure of the session, and is |
960 | called by the C<session> method if appropriate. |
961 | |
68fd02ae |
962 | =item create_session_id |
963 | |
bfa4f9cc |
964 | Creates a new session ID using C<generate_session_id> if there is no session ID |
68fd02ae |
965 | yet. |
966 | |
ab634fee |
967 | =item validate_session_id SID |
968 | |
969 | Make sure a session ID is of the right format. |
970 | |
971 | This currently ensures that the session ID string is any amount of case |
972 | insensitive hexadecimal characters. |
973 | |
229a5b53 |
974 | =item generate_session_id |
975 | |
976 | This method will return a string that can be used as a session ID. It is |
977 | supposed to be a reasonably random string with enough bits to prevent |
978 | collision. It basically takes C<session_hash_seed> and hashes it using SHA-1, |
bfa4f9cc |
979 | MD5 or SHA-256, depending on the availability of these modules. |
229a5b53 |
980 | |
981 | =item session_hash_seed |
982 | |
983 | This method is actually rather internal to generate_session_id, but should be |
984 | overridable in case you want to provide more random data. |
985 | |
986 | Currently it returns a concatenated string which contains: |
987 | |
988 | =over 4 |
989 | |
7048c24e |
990 | =item * A counter |
229a5b53 |
991 | |
7048c24e |
992 | =item * The current time |
229a5b53 |
993 | |
7048c24e |
994 | =item * One value from C<rand>. |
229a5b53 |
995 | |
7048c24e |
996 | =item * The stringified value of a newly allocated hash reference |
229a5b53 |
997 | |
7048c24e |
998 | =item * The stringified value of the Catalyst context object |
229a5b53 |
999 | |
1000 | =back |
1001 | |
bfa4f9cc |
1002 | in the hopes that those combined values are entropic enough for most uses. If |
229a5b53 |
1003 | this is not the case you can replace C<session_hash_seed> with e.g. |
1004 | |
1005 | sub session_hash_seed { |
1006 | open my $fh, "<", "/dev/random"; |
1007 | read $fh, my $bytes, 20; |
1008 | close $fh; |
1009 | return $bytes; |
1010 | } |
1011 | |
1012 | Or even more directly, replace C<generate_session_id>: |
1013 | |
1014 | sub generate_session_id { |
1015 | open my $fh, "<", "/dev/random"; |
1016 | read $fh, my $bytes, 20; |
1017 | close $fh; |
1018 | return unpack("H*", $bytes); |
1019 | } |
1020 | |
1021 | Also have a look at L<Crypt::Random> and the various openssl bindings - these |
1022 | modules provide APIs for cryptographically secure random data. |
1023 | |
8f236527 |
1024 | =item finalize_session |
1025 | |
1026 | Clean up the session during C<finalize>. |
1027 | |
1028 | This clears the various accessors after saving to the store. |
1029 | |
99b2191e |
1030 | =item dump_these |
1031 | |
1032 | See L<Catalyst/dump_these> - ammends the session data structure to the list of |
1033 | dumped objects if session ID is defined. |

1063 | =head1 USING SESSIONS DURING PREPARE |
1064 | |
1065 | The earliest point in time at which you may use the session data is after |
1066 | L<Catalyst::Plugin::Session>'s C<prepare_action> has finished. |
1067 | |
1068 | State plugins must set $c->session ID before C<prepare_action>, and during |
1069 | C<prepare_action> L<Catalyst::Plugin::Session> will actually load the data from |
1070 | the store. |
1071 | |
7048c24e |
1072 | sub prepare_action { |
1073 | my $c = shift; |

064c3709 |
1087 | }); |
9e447f9d |
1088 | |
1089 | All configuation parameters are provided in a hash reference under the |
064c3709 |
1090 | C<Plugin::Session> key in the configuration hash. |
9e447f9d |
1091 | |
1092 | =over 4 |
1093 | |
1094 | =item expires |
1095 | |
1096 | The time-to-live of each session, expressed in seconds. Defaults to 7200 (two |
1097 | hours). |
1098 | |
f30f78e8 |
1099 | =item expiry_threshold |
1100 | |
076c159b |
1101 | Only update the session expiry time if it would otherwise expire |
1102 | within this many seconds from now. |
f30f78e8 |
1103 | |
1104 | The purpose of this is to keep the session store from being updated |
1105 | when nothing else in the session is updated. |
1106 | |
1107 | Defaults to 0 (in which case, the expiration will always be updated). |
1108 | |
9e447f9d |
1109 | =item verify_address |
1110 | |
dd7f0872 |
1111 | When true, C<< $c->request->address >> will be checked at prepare time. If it is |
8c7e922c |
1112 | not the same as the address that initiated the session, the session is deleted. |
9e447f9d |
1113 | |
33641c1d |
1114 | Defaults to false. |
1115 | |
06c621b5 |
1116 | =item verify_user_agent |
1117 | |
dd7f0872 |
1118 | When true, C<< $c->request->user_agent >> will be checked at prepare time. If it |
af1e4bc8 |
1119 | is not the same as the user agent that initiated the session, the session is |
06c621b5 |
1120 | deleted. |
1121 | |
1122 | Defaults to false. |
1123 | |
68fd02ae |
1124 | =item flash_to_stash |
1125 | |
1126 | This option makes it easier to have actions behave the same whether they were |
1127 | forwarded to or redirected to. On prepare time it copies the contents of |
1128 | C<flash> (if any) to the stash. |

9e447f9d |
1142 | |
1143 | =item __updated |
1144 | |
d44bc687 |
1145 | The last time a session was saved to the store. |
9e447f9d |
1146 | |
1147 | =item __created |
1148 | |
1149 | The time when the session was first created. |
1150 | |
1151 | =item __address |
1152 | |
1153 | The value of C<< $c->request->address >> at the time the session was created. |
8c7e922c |
1154 | This value is only populated if C<verify_address> is true in the configuration. |
9e447f9d |
1155 | |
06c621b5 |
1156 | =item __user_agent |
1157 | |
e79a686c |
1158 | The value of C<< $c->request->user_agent >> at the time the session was created. |
06c621b5 |

1165 | =head2 Round the Robin Proxies |
1166 | |
c80e9f04 |
1167 | C<verify_address> could make your site inaccessible to users who are behind |
1168 | load balanced proxies. Some ISPs may give a different IP to each request by the |
1169 | same client due to this type of proxying. If addresses are verified these |
1170 | users' sessions cannot persist. |
1171 | |
1172 | To let these users access your site you can either disable address verification |
1173 | as a whole, or provide a checkbox in the login dialog that tells the server |
1174 | that it's OK for the address of the client to change. When the server sees that |
bfa4f9cc |
1175 | this box is checked it should delete the C<__address> special key from the |
c80e9f04 |
1176 | session hash when the hash is first created. |

1180 | In this day and age where cleaning detergents and Dutch football (not the |
1181 | American kind) teams roam the plains in great numbers, requests may happen |
a552e4b5 |
1182 | simultaneously. This means that there is some risk of session data being |
1183 | overwritten, like this: |
1184 | |
1185 | =over 4 |
1186 | |
1187 | =item 1. |
1188 | |
bfa4f9cc |

a552e4b5 |

1193 | session data is loaded in request a |
1194 | |
1195 | =item 3. |

1197 | session data is loaded in request b |
1198 | |
1199 | =item 4. |
1200 | |
1201 | session data is changed in request a |
1202 | |
1203 | =item 5. |
1204 | |
1205 | request a finishes, session data is updated and written to store |
1206 | |
1207 | =item 6. |
