@hackage wai-session-maybe1.0.0

Provides a generic, cookie-based middleware for sessions that is parameterised over the session store, the cookie name, and the cookie parameters (such as path, expiry, etc). Passes a pair of functions (lookup key, set key) for the current session through the 'Vault' in the 'Request'.

Also provides a simple example session store based on threadsafe 'IORef's and 'Data.Map'.

See example/Main.hs in git for example usage.
