Hi, Those are dynamic pages, but their URLs to not contain any query parameters. The home page is a good example for a URL that is database driven. In addition URLs like those: mydomain.com/san-francisco mydomain.com/los-angeles mydomain.com/whats-hot Etc. Those are all dynamic pages with file URLs. Skipping URLs with query parameters is fine, they only happen after form submissions which we prefer not to cache.
