OK, got it working. I checked my apache logs and discovered that it was getting an error related to CURL. I didn’t have CURL installed, so a quick apt-get install php5-curl and an apache restart and its now uploading all of my content into my S3 bucket.
One last question:
Should I use the amazonaws.com address for the host, or should I setup my own DNS entry to point to that?
Thanx,
OLIVER
