Hi,

Thanks for chiming in, Andy! I realized yesterday that I should have added how some URLs can be retrieved without problem in BaseX-10.0, e.g.:

  let $uri := 'https://www.w3.org'
  return http:send-request(<http:request method="get" status-only="true" href="{$uri}"/>)

...which is well-formed (to rule out non-XML parser issues), and indeed has no redirection, which seems consistent with Andy's observation. Yet, https://w3.org also is retrieved successfully, which has an initial 301 response (instead of 303).

Best,

Ron

What I have assessed so far is that it’s the Java Client that fails to
retrieve the result. It’s the same response that’s returned by BaseX.

String uri = "http://vocab.getty.edu/aat/300027473.rdf";
HttpClient client = HttpClient.newBuilder().build();
HttpRequest request = HttpRequest.newBuilder(URI.create(uri)).build();
BodyHandler<String> handler = HttpResponse.BodyHandlers.ofString();
HttpResponse<String> result = client.send(request, handler);
System.out.println(result.statusCode());
System.out.println(result.body());

400

So we need to find out why the server thinks the Java request is
»syntactically incorrect«. Maybe we can compare the low-level
representation of the requests with Java 9 and 10 (?).
