Amazon s3 - Call file after upload

Question

I'm using a php script to upload a file to Amazon S3

$s3->putObjectFile($url,$bucket,$filename, S3::ACL_PRIVATE,array(),array("Content-Type" => "application/json"));

Immediately after the upload, I need to get some information from the file and I call it through Cloudfront but I see that the file is available only after some minutes.

Do you know why and if there is a way to sort this out? Is there a way to have the file immediately available?

Thank you

Answer 1

It was immediately available for me with this test...

$ date;aws s3 cp foo s3://BUCKET/foo;date;curl -I http://dxxx.cloudfront.net/foo;date

upload: ./foo to s3://BUCKET/foo

Perhaps your upload is happening asynchronously and the upload hadn't completed yet?
