Session and adding cookie headers

[Bill Moseley]

Is it the intended behavior  to set a cookie any time the session is *fetched* even if nothing is set in the session?

With a new  app with these added plugins:

    Cache
    Session
    Session::Store::Cache
    Session::State::Cookie

And if I just add my $ses = $c->session; to the index action in root then that causes a Set-Cookie header to be set in the response. (And if cookies are disabled on a browser then a new session id is created every request, and expires is written to the store).

Not a big deal, but just curious if that was by design or just a side-effect of how the session code works.

I typically use session cookies and don't set a cookie header in the response if a valid session id was in the request cookie.

I wouldn't say that it is intended behaviour, but it is behaviour that
is used in the C::P::Session test suite.

When you check for a session using $c->session a session is created
and then persisted on the browser using a cookie. There is no logic to
check if there is anything interesting stored in the session (ie that
it is not a 'null session').

You might want to look at the following code which I wrote a while
back and added to the repo but never released to CPAN - it would just
muddy the waters:

It tries not to do anything silly :)

Cheers,
  Edmund.
