When your gateway listen on the standard https port (443), you are tempted to define baseurl the following way :
<property name="unicore.wsrflite.baseurl" value="https://gateway/VSITE/services"/>
But this syntax makes unicore/x not working anymore and log/uas.log becomes full of:
INFO DefaultOnStartup - Waiting for gateway...
WARN SecurityManager - Can't get certificate for <https://gateway/VSITE/services>, maybe the server is not running?
Making wsrflite using default HTTP port (443) if not mentionned in wsrflite.xml could avoid some hard time to sysadmins :)
