Hi Andrea,
The VRT is an XML format and hence you need to ensure the content is XML
compliant: your URL contained `&` characters that need to be escaped to
`&`. The following VRT works for me:
<OGRVRTDataSource>
<OGRVRTLayer name="OGRGeoJSON">
<SrcDataSource>http://www.provincia.caltanissetta.sitr.it/ArcGIS/rest/services/Immobili/MapServer/0/query?where=objectid+%3D+objectid&outfields=*&f=json</SrcDataSource>
<LayerSRS>EPSG:3004</LayerSRS>
<SrcLayer>OGRGeoJSON</SrcLayer>
</OGRVRTLayer>
</OGRVRTDataSource>
Best regards,
Homme
