Hi Jakob,
The if around the xdmp:http-head doesn’t do anything, the function returns item()+. But otherwise I guess it should work. Regardless of the service you try to connect, I would expect the function to return a response. And a 404 is also a response. J Only if there is nothing behind the port, you will get a SOCSERV exception or alike. So, I guess you are reasonably safe like this..
