libdata-session-perl - 1.18-2 main

Data::Session is typically used by a CGI script to preserve state data between
runs of the script. This gives the end user the illusion that the script never
exits.
.
It can also be used to communicate between 2 scripts, as long as they agree
beforehand what session id to use.
.
See Data::Session::CGISession for an extended discussion of the design changes
between Data::Session and CGI::Session.
.
Data::Session stores user data internally in a hashref, and the module
reserves key names starting with '_'.
.
The current list of reserved keys is documented under "flush()". Of course,
the module also has a whole set of methods to help manage state.
