Hello,

I'm trying to post a SPARQL query to an endpoint using Digest authentication with the HTTP client.

The query works fine using curl:

curl --digest --user user:pass -X POST -d@'test.rq' \
-H "Content-type: application/sparql-query" \
'http://example.org/sparql'

But the equivalent request in BaseX fails with 401 Unauthorized:

let $endpoint := "http://example.org/sparql"
let $user := "user"
let $pass := "pass"
let $type := "application/sparql-query"

let $response := (
http:send-request(
<http:request
method="POST"
href="{$endpoint}"
username="{$user}"
password="{$pass}"
auth-method="Digest"
send-authorization="true">
<http:header
name="Content-Type"
value="{$type}; charset=utf-8"/>
<http:body
media-type="{$type}">{
``[
select * where {?s ?p ?o} limit 1
]``
}</http:body>
</http:request>
)
)
return
$response

Any ideas about what might be causing the BaseX HTTP client to be denied here?

Thanks in advance,

Tim
