Great stuff Sawyer, thank you! I had a look at Dancer2::Session::Memcached, and just realized that I only really need to store a session token (from a 3rd party service that the bot interacts with). So I probably only have to use Dancer2::Session::Cookie. Let's see how to integrate that elegantly into the design...
If I even need to store a whole object in the future, I'll know where to look. --- Pierre Masci I check email a couple times daily; to reach me sooner, you can send me a text message via this page: https://awayfind.com/mascip On 6 December 2013 11:53, sawyer x <xsawy...@gmail.com> wrote: > Every request from the web server generates a call to the application code > reference that is built by "dance".
