Method TryRefreshSessionAsync

TryRefreshSessionAsync(TSessionToken, SessionRecord, int, CancellationToken)

Updates the session that the specified session token belongs to with the values of refreshedSession, if its stored generation is still expectedGeneration. Returns true if the session was updated, or false if it no longer exists or its generation has changed.

Declaration

Task<bool> TryRefreshSessionAsync(TSessionToken sessionToken, SessionRecord refreshedSession, int expectedGeneration, CancellationToken cancellationToken)

Parameters

Type	Name	Description
TSessionToken	sessionToken	The token of the session to update.
SessionRecord	refreshedSession	The values to store: Device, IpAddress, RefreshedUtc, ExpiresUtc and Generation. Its CreatedUtc and IsPersistent are the stored values, which never change.
int	expectedGeneration	The generation the stored session must have for the update to be applied.
CancellationToken	cancellationToken	A token to cancel the operation.

Returns

Type	Description
Task<bool>

Remarks

The generation check and the update must be atomic, such as a single conditional update statement, so that only one of several concurrent updates of the same generation succeeds. The generation of refreshedSession can be the same as expectedGeneration.
