    Description

      Moodle xmlrpc server returns content-length:0 header with non-empty content. For some reason https://moodle.net server strips out content completely in this case, probably because of the web-server (it uses nginx) or other software involved in page serving.

      This results with error not being returned to sites that try to register.

      Another challenge that this can not be reproduced in local/testing environments - header "content-legth:0" is just ignored and full response body is returned
