Hi,

After upgrading BaseX to 10.0 (yay!), I notice how http:send-request() calls that used to work in 9.7 are now failing. I didn't find any changes documented between version 9.7 and 10.0 at https://docs.basex.org/wiki/HTTP_Client_Module. Yet (tested with the same JDK), I'm observing differences between BaseX-9.7 and BaseX-10.0.

Test case: 

  let $uri := 'http://vocab.getty.edu/aat/300027473.rdf'
  return http:send-request(<http:request method="get" status-only="true" href="{$uri}"/>)

Result:

• BaseX-9.7: valid response
  

  <http:response xmlns:http="http://expath.org/ns/http-client" status="200" message="OK">
    <http:header name="Server" value="Apache-Coyote/1.1"/>
    <http:header name="Content-Disposition" value="attachment; filename=&quot;aat_300027473.rdf&quot;"/>
    <http:header name="Set-Cookie" value="BIGipServerForest=!VhOKP5OjryEOuPhyk3Vb4l5ey77Ecb9C7h36RwDl7h0P+12yggqrxtSz6mEpwv8Du1qdIeJTRfFkqw==; path=/; Httponly"/>
    <http:header name="Content-Length" value="55888"/>
    <http:header name="Date" value="Thu, 04 Aug 2022 14:32:02 GMT"/>
    <http:header name="Content-Type" value="application/rdf+xml;charset=UTF-8"/>
    <http:body media-type="application/rdf+xml"/>
  </http:response>

• BaseX-10.0: "Bad Request" error
  

  <http:response xmlns:http="http://expath.org/ns/http-client" status="400" message="Bad Request">
    <http:header name="connection" value="close"/>
    <http:header name="content-length" value="968"/>
    <http:header name="content-type" value="text/html;charset=utf-8"/>
    <http:header name="date" value="Thu, 04 Aug 2022 14:31:56 GMT"/>
    <http:header name="server" value="Apache-Coyote/1.1"/>
    <http:header name="set-cookie" value="BIGipServerForest=!mBtphfxjdsqnz+Vyk3Vb4l5ey77EcVUpOTC6kqayu7tj3BpCNxN68oQTs+W4wrEO4+vQ2pECmIF6rA==; path=/; Httponly"/>
    <http:body media-type="text/html"/>
  </http:response>

The same results are obtained with fetch:xml() (BaseX-9.7 - valid response) and fetch:doc() (BaseX-10.0 - bad request).

Apologies if I'm overlooking the obvious, but has anything changed w.r.t. these http / fetch module functions or their underlying methods of network access that would require changes in my XQuery code or BaseX-10.0 configuration?

Best,

Ron
