Examples of de.javakaffee.web.msm.SessionIdFormat

de.javakaffee.web.msm.SessionIdFormat
This class defines the session id format: It creates session ids based on the original session id and the memcached id, and it extracts the session id and memcached id from a compound session id.
The session id is of the following format: [^-.]+-[^.]+(\.[^.]+)?
