I'm using HTTP::DAV to upload files to Plone. It's pretty simple, and used to work in Plone3. Something like: 

$dav = new HTTP::DAV;
$dav->credentials("foo","bar",$url");
$dav->open($url);
$dav->put($file);

If I try this with Cadaver in Plone4, I get an HTTP 500 error if I try to upload a file that does not exist on the server. If the file does exist; I get a 401 not authorized response, cadaver re-tries with the credentials and then presents the credentials on every subsequent request and is able to upload a file that does not already exist.

In HTTP::DAV, the credentials are never presented - at least in my simple calls - without a prior 401 response, so I can never upload a new file.

This is arguably a bug in Plone4, and I have reported it, but meanwhile my system is broken. Is there a way to tell HTTP::DAV to present credentials promiscuously ?
