Dancer2 plugin to defer messages or data across redirections

This Dancer2 plugin provides a method for deferring a one-time message across a redirect. It is similar to “flash” messages, but without the race conditions that can result from multiple tabs in a browser or from AJAX requests. It is similar in design to CatalystPluginStatusMessage, but adapted for Dancer2.

It works by creating a unique message ID within the session that holds deferred data. The message ID is automatically added as a query parameter to redirection requests. It’s sort of like a session within a session, but tied to a request rather than global to the browser. It will even chain across multiple redirects.
