is there any way to update files stored on Amazon's CDN service? Seems like it won't take any update of a file we make (eg. removing the file and storing the new one with the same file name as before). Do I have to explicitly trigger an update process to remove the files from the edge servers to get the new file contents published?

Thanks for your help

Matt

Do not use the same name.

You're supposed to use a new name for new versions of the same file.

  1. logo.png--0
  2. logo.png--1 etc...

They will cache like you have noticed. This is by design.

For the record, Amazon does have a 24 hour cache on the S3 service, so it might take some time until your new image shows up.

As far as I know, Amazon itself recommends filename versioning if you have content that updates faster than a 24 hour cycle allows.
