Note Submitter: chris at ocproducts dot com ---- Never provide a CURLOPT_CUSTOMREQUEST value of 'HEAD'. It will cause cURL to timeout. Instead set CURLOPT_NOBODY to true. The problem occurs because CURLOPT_CUSTOMREQUEST directly substitutes what cURL sends in transit, but not the response handling logic. It causes it to stall waiting for data that will never come.
