Apache reçoit les demandes au port 80 et les envoie à Jetty au port 8080
The proxy server received an invalid response from an upstream server
The proxy server could not handle the request GET /.
Mon dilemme: Tout fonctionne très bien normalement (demandes rapides, quelques secondes ou quelques dizaines de secondes demandes longues sont traitées ok ). Des problèmes surviennent lorsque le traitement d'une demande prend beaucoup de temps (quelques minutes?).
Si j'émets la demande directement à Jetty au port: 8080, la demande est traitée correctement. Donc, le problème est susceptible de se situer quelque part entre Apache et Jetty où j'utilise mod_proxy . Comment résoudre ceci?
J'ai déjà essayé quelques "astuces" relatives aux paramètres KeepAlive, sans succès. Voici ma configuration actuelle, des suggestions?
#keepalive Off ## I have tried this, does not help
#SetEnv force-proxy-request-1.0 1 ## I have tried this, does not help
#SetEnv proxy-nokeepalive 1 ## I have tried this, does not help
#SetEnv proxy-initial-not-pooled 1 ## I have tried this, does not help
KeepAlive 20 ## I have tried this, does not help
KeepAliveTimeout 600 ## I have tried this, does not help
ProxyTimeout 600 ## I have tried this, does not help
