1. web server
| division | directive | default | explanation |
| HTTP | Timeout | 300 | Sets how long an HTTP connection will be kept alive for an inactive connection. |
| KeepAliveTimeout | 15 | Sets the amount of time an Apache process (or thread) should wait before a client sends another HTTP request. | |
| mod-jk | socket_timeout | 0 | Timeout used in the communication channel between mod-jk and was. An error occurs if there is no response for a set period of time. |
| socket_connect_timeout | socket_timeout*1000 | Same as socket_timeout, but you can set the timeout in milliseconds. | |
| socket_keepalive | FALSE | Used when there is a firewall between the web server and WAS. This flag prevents the firewall from closing inactive connections by sending a KEEP_ALIVE message to the operating system for inactive connections. | |
| ping_timeout | 10000 | Timeout value in milliseconds. It is used when waiting for CPong, which is the response of Cping connection confirmation. | |
| reply_timeout | 0 | Waiting time until response comes after WAS is processed in WEB | |
| connection_pool_timeout | 0 | The Cache timeout property is used in conjunction with connection_pool_minsize to determine how many seconds mod-jk will keep the cache's inactive sockets open before closing the connection. |
