The URL passed by a HTTP request to invoke a servlet. The URL consists of the Context Path + Servlet Path + PathInfo, where Context Path is the path prefix associated with a servlet context that this servlet is a part of. 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 which activated this request. This path starts with a / character. PathInfo is the part of the request path that is not part of the Context Path or the Servlet Path.
