"The PHP curl library [...] uses a special HTTP 1.1: 100 (Continue) 
Status on POST requests, that have a certain size. Some webservers (like 
lighttpd) do not support this behaviour and return HTTP error codes (417 
in case of lighttpd)."

Experts disagree on whose fault it is (curl's or lighttpd's).

The problem can be fixed by patching lighthttpd (problem is reportedly 
fixed for 1.5 in SVN), or by patching curl, or by manually setting the 
header to nothing from PHP like this:

   curl_setopt($curl_handle, CURLOPT_HTTPHEADER, array('Expect:'));

Bye
