Using if-modified-since relies on the server you're querying supporting that - but if you do use it you set If-Modified-Since (see: https://tools.ietf.org/html/rfc7232#section-3.3) and if you receive a HTTP 304 Not Modified the remote object was not newer than your requested date (see: https://tools.ietf.org/html/rfc7232#section-4.1). > Anyone know the call/header value to use for getting at the remote > object's last-modified time directly? You can check what headers are available by using a HEAD request before you GET - then you can make the call to download or not.
