Unfortunately, this is not true. The msg only contains the text
information in the status line of the HTTP reply. If I'm not
mistaken, the exception is created in this line in std/net/curl.d:
enforce(statusLine.code / 100 == 2, new
HTTPStatusException(statusLine.code,
format("HTTP request returned status code %d (%s)",
statusLine.code, statusLine.reason)));
If anything is wrong, the server I'm interested in tends to reply
with a status code 500 and a generic status line text and a
bloated XML body containing the actual error message.
