Petit article rapide sur un probl\u00e8me que j’ai rencontr\u00e9 cette semaine sur ma boutique personnelle Prestashop.
Ou il m’\u00e9tait impossible d’acc\u00e9der \u00e0 la fois au front et au back office car je rencontrais une erreur 431.
Ce probl\u00e8me ne se produisait qu’en \u00e9tant connect\u00e9 et pas en navigation priv\u00e9e.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Le message d’erreur est assez explicite, trop d’informations \u00e9taient envoy\u00e9es dans l’ent\u00eate de la requ\u00eate.
Apache n’arrivait plus \u00e0 lire l’ensemble des d\u00e9tails de la requ\u00eate.
Et le point bizarre c’est qu’en plus il me loguait l’acc\u00e8s \u00e0 cette page dans un autre vhost que le normal.
Apr\u00e8s analyse la cause de l’erreur \u00e9tait la taille des cookies envoy\u00e9s.
J’avais 8 cookies diff\u00e9rents de sessions Prestashop envoy\u00e9es simultan\u00e9ment ce qui surchargeait les headers.

La solution pour corriger \u00e9tait relativement simple : Supprimer l’ensemble des cookies pour le domaine dans le navigateur.
Ensuite tout fonctionnait \u00e0 nouveau comme pr\u00e9vu.<\/p>\n","protected":false},"excerpt":{"rendered":"
