This bug might belong in the URL-related section.
I believe it to be a generic problem.

If you fopen() an URL
that returns with an HTTP Header of NoContent (204),
fopen() will fail with Error 0.

Failure would be ok if there was a specific error
code for NoContent URLs.  Either that or returning
a handle that was already at eof would suffice.
As it is now, there's no way to tell the difference
between a bad (NotFound) URL and a NoContent URL.

Work-around it to use cURL to a temporary file
and check the HTTP_CODE with the undocumented
curl_getinfo() function.  Of course, it seems
a little weird to require the temporary file 
for a NoContent URL.  But it works fine.

Taken from #9847, these are basically the same problem:

    When fopen()-ing an URL that responds
    with an HTTP 403 Forbidden, fopen()
    fails with an Error 0.   There is no
    way to distinguish this error from
    a 'Not Found' type of error.

Doesn't the contents of $http_response_header tell you
what you need? $http_response_header should be an array
of the HTTP response fopen() got

No feedback. Closing.
