If you have more than 4K of session data or don’t want your data to be visible to the user, pick another session store.

CookieOverflow is raised if you attempt to store more than 4K of data. TamperedWithCookie is raised if the data integrity check fails.

A message digest is included with the cookie to ensure data integrity: a user cannot alter session data without knowing the secret key included in the hash.

To use Cookie Sessions, set in config/merb.yml 

:session_secret_key - your secret digest key
:session_store: cookie
