Detailed Description

Storage for all sessions known

This is a simple storage for sessions.

Sessions are thread safe to use.

The sessions themselves are not created until some data is written to it by the program. This way we avoid "session attack" where a malicious user sends many petitions asking for new sessions.

FIXME to add some LRU so that on some moment we can remove old sessions.
