Re: [Exist-open] eXist EXPath HTTP client - problem with order of response

On a related note, is it correct that a simple request like: http:send-request(<http:request method="GET" href="http://exist-db.org/"/>) should return an NPE? I've saved this query as /db/http-test.xq and run as http://localhost:8080/exist/apps/http-test.xq, and here's the NPE error: HTTP ERROR 500 Problem accessing /exist/apps/http-test.xq. Reason: An error occurred: null Caused by: javax.servlet.ServletException: An error occurred: null at org.exist.http.servlets.EXistServlet.doGet(EXistServlet.java:367) at
