Hi,

i want to use the remote_file resource sunch that the client does not download the file if file size is same, is there something extra i have to do or remote_file is idempotent by default ?

I was looking at documentation, its confusing at some places it says use_conditional_get , but again there are no examples on how to use it.

Thanks

If you're on Chef 11.6.0+, and your HTTP server supports ETag and/or If-Modified-Since, Chef will handle use those HTTP features automatically to avoid unnecessary downloads.

If you're on an earlier version of Chef, or your HTTP server doesn't implement those cache control features, you need to provide a SHA2-256 checksum of the file in the resource's checksum attribute.
