Let's say I have a URL which points to a file on an HTTP server that is constantly being appended to.
Could [lib]curl not efficiently poll (at a prescribed interval) that URL looking for newly appended content using whatever mechanism is behind the -C option? If nothing new was added it should be GET with no content but if something new was added, the effective -C option would only get the new content which would be sent to stdout (or a file for -o/-O). Is there something about HTTP that I'm missing that would make this not work? b.
