In response to intercepting an initial call for a transaction for a service from a client, a token is validated for the initial call of the transaction for the service, the validating including contacting an authentication sever and locally storing a time to live received for the token. In response to intercepting at least one successive call for the transaction for the service from the client, it is determined that the token for the at least one successive call is valid based on the time to live locally saved. The at least one successive call for the transaction for the service is permitted to pass without contacting the authentication sever.
