Make the request out to be a POST, like use CURLOPT_POSTFIELDS or
CURLOPT_READFUNCTION or whatever you think is the best way.

Then you alter the method to a GET with CURLOPT_CUSTOMREQUEST and you should
be good to go. You may want to remove/alter the "Content-Type:" that a mere
POST will make libcurl use by default (use CURLOPT_HTTPHEADER for that).
