Just upgraded to Rails 3 from 2.x. I've got a download method which returns a file for download via XSendfile. In Rails 2.x a HEAD request of the download resulted in a response which included Content-Length, ETag and Last-Modified headers, but in Rails 3 I'm not longer getting these. Reading the HTTP spec, these should be there. Any idea what's going wrong and how to fix it?
I'm running with Passenger. And my other rails 2 apps with the same method continue to provide the missing headers.
Thanks.
