Hi All,
I've tried setting my own cookie with Dancer2 and also setting the session engine as Cookie.
I'm using Windows 32 Bit (under Cygwin), with Perl 5.22
Dancer2::Session::Cookie - 0.006
Dancer2 - 0.0161000
Dancer2::Core::Cookie - 0.16000
Although I couldn't find a lot on the Dancer2 method, there is a bit on how to do this with Dancer1.
