User authentification Sample Clauses

User authentification. The LSF front-end is session-based. In order to use the system, an authentification is needed. This is done in the session-scoped managed bean. A servlet filter is created to check for each request if the request is authorized, if not, the user is redirected to the login page. For the RESTful web services, the authentication mechanism is different since no graphical user interface is needed there. The authentication information is embedded in the HTTP header. Each RESTful client has its own API key. The API key is needed for each HTTP request.‌
