The Cacheability Engine will check a URL you feed it for several things that will affect a Web cache, including web server clock skew, expires and Cache-Control headers, Last-Modified date presence, validation of LM date, Content-Length presence and more. It makes it easy to see how a cache will treat your content. There are also public engines running, so you don't have to install the software to use it for Internet-available sites.
