I want to maintain a "session" (i.e. collection of server-side variables) for each open browser window (not browser "session" in the technical sense).

I implemented such a mechanism as a Dancer Plugin: Dancer::Plugin::WindowSession .

See it in action here:
  http://winsid.cancan.cshl.edu/

The source code for the plugin (and the demo) are here:
  https://github.com/agordon/Dancer-Plugin-WindowSession
(and soon in CPAN).


On the Perl side, simply use "window_session" keyword instead of "session" keyword.
On the template side, you'll need to pass along the "winsid" (=window session id) as a CGI parameter to every URL and POST request.

See code example here (that's the method that generates the plot for the demo):
https://github.com/agordon/Dancer-Plugin-WindowSession/blob/master/eg/example/lib/window_session_test.pm#L28

It uses the same session mechanism defined in the config.yml, and only uses standard Dancer keywords (no ugly hacking),
so I hope it will be stable and portable for Dancer2 .

Comments are welcomed,
