Any request to an ArcWeb service needs to include validating information that the request is coming from an authorized ArcWeb user. Authentication Web Service tokens allow you to pass this authentication information in an encrypted and secure state. See Authentication Web Service overview for details about using tokens from Authentication Web Service.
As an alternative to using tokens from Authentication Web Service, .NET and Axis toolkit users can include authentication information via a WS-Security header. See ArcWeb Services Authentication for more information.
Length of the authentication token stringThe authentication token string length is variable, depending on the length of the information it is encoding.
Use the method validateToken to determine if a new token needs to be generated for an upcoming request. This helps make token regeneration seamless to an application end user.
