Bonjour,
je viens sur ce forum pour un problème qui m’a pris une journée sans trouver de solutions.
J’ai configuré squid 3.1.8 sur une Debian 7 et lancé l’essai sur une seule machine en indiquant le proxy dans le navigateur.
Mais, les logs qui indique l’accès au proxy sont pleins de TCP_MISS et TCP_REFRESH_UNMODIFIED quand le réactualise une page déjà visitée. Or, en cherchant la signification de ce mot-clé, j’ai remarqué que cela signifie que l’objet cherché est absent du cache.
voici la sortie après réactualisation d’une page, de ::
[i]Tail -f /var/log/squid3/access.log

Néanmoins si je regarde la taille du cache, il augmente au fil de la navigation (mais timidement):
du -hs /var/spool/squid3/
28M /var/spool/squid3/
si je cherche les logs contenant TCP_HIT, ils ne sont que très peu et ne concerne apparemment que des images et cela pas pour tous les sites visités:
cat /var/log/squid3/access.log | grep TCP_HIT

Quelqu’un aurait une idée de pourquoi certains éléments sont seulement cachés?
