Thanks, Christian. Right, that wasn't a working example. The server I'm querying is behind a firewall, so I can't really reproduce the issue unfortunately.

The BaseX documentation states that the HTTP client does support Digest authentication. However, I did some poking around using Wireshark and limited knowledge of network traffic. When I run the request in curl, the expected protocol is played out, and I see the evidence in Wireshark:

(1) The server responds with "401 Unauthorized" and provides the nonce value.

(2) The client (curl) then does its business (supplies the username and password, resends the request, etc.)

But when I submit the request via BaseX, it never gets past step (1). It never seems to send the username and password at all. Is Digest authentication still supported?

Best,

Tim

Hi Tim,

Difficult to tell; both the curl and the XQuery variants give me 404.
Do you think you could provide us with an example that works out of
the box?

Best,
Christian
