Estimadas, estimados, ¡ya estamos de vuelta!

Tras dos meses de parón blogosférico, durante los cuales he andado bastante atareado con otros menesteres, volvemos a la carga. Y no había mejor forma de hacerlo que publicando la entrega número 412 de la serie de enlaces interesantes, que seguro echabais de menos cada lunes ;)

Y por cierto, ya que ha salido el tema, el código de error HTTP 412 (Precondition failed) se produce cuando el acceso a un recurso es denegado debido a que no se cumplió algunas de las precondiciones especificadas a través de encabezados como If-Match, If-Modified-Since, If-None-Match o similares. El objetivo es evitar la ejecución de la acción (GET, POST, etc.) sobre un recurso que se encuentra en un estado incorrecto.

Por si te lo perdiste...
