Descriptions

plone.rest allows users to use HTTP verbs such as GET, POST, PUT, DELETE, etc. in Plone. Starting in the 2.x branch and prior to versions 2.0.1 and 3.0.1, when the `++api++` traverser is accidentally used multiple times in a url, handling it takes increasingly longer, making the server less responsive. Patches are available in `plone.rest` 2.0.1 and 3.0.1. Series 1.x is not affected. As a workaround, one may redirect `/++api++/++api++` to `/++api++` in one's frontend web server (nginx, Apache).

plone.rest permite a los usuarios utilizar verbos HTTP como GET, POST, PUT, DELETE, etc. en Plone. A partir de la rama 2.x y antes de las versiones 2.0.1 y 3.0.1, cuando el recorridor `++api++` se usa accidentalmente varias veces en una URL, su manejo lleva cada vez más tiempo, lo que hace que el servidor responda menos. Los parches están disponibles en `plone.rest` 2.0.1 y 3.0.1. La serie 1.x no se ve afectada. Como workaround, se puede redirigir `/++api++/++api++` a `/++api++` en el servidor web frontend (nginx, Apache).
