- Method Detail
  - login
```
void login()
```
    Checks weather the credentials in the authorization string match an existing User Account, and if so, creates an HTTP session. ### FIXDOC
    
    Parameters:
    
    authHeader - the authorization string containing the credentials. ### FIXDOC Formatted like a "Authorization" HTTP header value. That is, "Basic " appended by the Base64 encoded form of "{username}:{password}".
  - logout
```
void logout()
```
    Logs the user out. That is invalidating the session associated with the JSESSION ID cookie. For a "non-private" DM installation the response is 204 No Content. For a "private" DM installation the response is 401 Authorization Required. In this case the webclient is supposed to shutdown the DM GUI then. The webclient of a "private" DM installation must only be visible/usable when logged in.
