A request for: http://some.server.com//nodesecurity.org/%2e%2e would result in a 301 to //nodesecurity.org/%2e%2e which most browsers treat as a proper redirect as // is translated into the current schema being used. Mitigating factor: In order for this to work, st must be serving from the root of a server (/) rather than the typical sub directory (/static/) and the redirect URL will end with some form of URL encoded ..

Una petici\u00f3n para: http://some.server.com//nodesecurity.org/%2e%2e resultar\u00eda en un error 301 a //nodesecurity.org/%2e%2e, el cual se considerar\u00eda una redirecci\u00f3n correcta por la mayor\u00eda de navegadores. Esto se debe a que // se traduce en el esquema actual en uso. Factor mitigador: para que esto funcione, st debe estar sirviendo desde el root de un servidor (/) en lugar del t\u00edpico subdirectorio (/static/) y la URL de redirecci\u00f3n debe terminar con alg\u00fan tipo de URL cifrada en ..
