Yep. If the GET has If-Modified-Since, then the server should send the body with 200 status or an empty 304 header.

With HEAD, the server should just send the header. If the content's changed, the bot would need to ask again with a GET.

Scott, click control panel [webmasterworld.com], then Server Headers [webmasterworld.com]. If there's a Last-Modified header then it should be cache friendly.
