URL structure distinguishes subdomains from directory paths. A subdomain appears before the main domain, like cars.about.com or blog.about.com, and acts as a separate host under the same domain. A directory path appears after the main domain, starting with a slash, such as about.com/cars, which points to a folder or section within the main site. The root domain about.com has no trailing path. Therefore, about.com/cars is the pattern that represents a directory path, not a subdomain.
