I was trying to use memcache for session storage in Typo. And i got
following error, when user logs into the system.

  Session ID:

This overkill of using memcache for session storage is because, I have
modified typo for hosting multiple blogs. The app works when i switch
to active_record storage.

Also, Users model of typo actually makes connection to one other apps
database, using establish_connection method of activerecord.

But why is this inconsistency.
