FetchExistingOrMakeNewSession(WorkContext, Boolean)
Override to get session object using whatever parameters are available in response context (i.e. a cookie),
or create a new one if 'onlyExisting'=false(default)
Declaration
protected virtual void FetchExistingOrMakeNewSession(WorkContext work, bool onlyExisting = false)
Parameters
| Type |
Name |
Description |

MakeNewSession(WorkContext)
Called to create a new session
Declaration
protected WaveSession MakeNewSession(WorkContext work)
Parameters
Returns
MakeNewSessionInstance(WorkContext)
Override to create a new session instance
Declaration
protected virtual WaveSession MakeNewSessionInstance(WorkContext work)
Parameters
Returns
StowSession(WorkContext)
Override to put session object back into whatever storage medium is provided (i.e. DB) and
respond with appropriate session identifying token(i.e. a cookie)
Declaration
protected virtual void StowSession(WorkContext work)
Parameters
TryMakeSessionFromExistingLongTermToken(WorkContext)
Override in session filters that support long-term tokens.
This method tries to re-create "existing" session from a valid long-term token, otherwise
null should be returned (the base implementation)
