A URL path basically consists of the context path + servlet path + path info, where Context path is the path prefix associated with a servlet context of which the servlet is a part. The path of a URL passed by an HTTP request to invoke a servlet. If this context is the default context rooted at the base of the Web server\'s URL namespace, the path prefix will be an empty string. Otherwise, the path prefix starts with a / character but does not end with a / character. Servlet path is the path section that directly corresponds to the mapping that activated this request. This path starts with a / character. Path info is the part of the request path that is not part of the context path or the servlet path.
