## Events

                            bool isClient = true)
```

The above: constructs a new ticket given a particular identity. The identity should be the User or Game Server that this ticket will be used by. Note that a lobby is not a server.

```csharp
public AuthenticationTicket(byte[] dataToInclude, 
                            Action<AuthenticationTicket, bool> callback)
```

The above: constructs a new ticket given existing ticket data

```csharp
public AuthenticationTicket(string webIdentity, 
                            Action<AuthenticationTicket, bool> callback)
```

The above: constructs a new ticket for a web identity, this string can be empty and is defined by the web service that will be using the ticket.
