User handling can be realized with session attributes (see e. g. the [[DBA]] code). By default, RESTXQ code is run with admin permissions. However, as it is more interesting to know which user has called a function, the RESTXQ user string (which is {{Code|admin}} by default, and which will show up in the log data) will be overwritten by the value of an {{Code|id}} session attribute. If the request path includes {{Code|/dba/}}, the {{Code|dba}} session attribute will be assigned. If the following function is called more than once, {{Code|joe}} will appear as user in the second and subsequent log entries: <pre class="brush:xquery">import module namespace Session = 'http://basex.org/modules/session';declare %rest:path('/session-id') function local:f() { Session:set('id', 'joe'), 'I am Joe'};</pre>
