By default this read buffer is sized at bytes. For lower concurrency, you can increase this to buffer more data. For an extreme amount of keep alive connections, decrease this number or increase your heap size. By default this write buffer is sized at bytes. For low concurrency you can increase this to buffer more response data. The default value here is pretty low, you should up it if you are not dealing with tens of thousands concurrent connections.
To reduce garbage collection, the NIO connector caches these channel objects. This value specifies the size of this cache. The default value is , and represents that the cache will hold NioChannel objects. Other values are -1 for unlimited cache and 0 for no cache. The integer value specifies how many objects to keep in the cache at most.
The default is Use this option when the command line org. NioSelectorShared value is set to false. Default value is When a selector is returned to the pool, the system can decide to keep it or let it be GC'd.
Default value is -1 unlimited. The following command line options are available for the NIO connector: -Dorg. Set this value to false if you wish to use a selector for each thread. When you set it to false , you can control the size of the pool of selectors by using the selectorPool. Duration of a poll call in microseconds. Lowering this value will slightly decrease latency of connections being kept alive in some cases , but will use more CPU as more poll calls are being made.
The default value is 2ms. Amount of sockets that the poller responsible for polling kept alive connections can hold at a given time. Extra connections will be closed right away. The default value is , corresponding to keep-alive connections. The proxyName and proxyPort attributes can be used when Tomcat is run behind a proxy server.
These attributes modify the values returned to web applications that call the request. Without configuring these attributes, the values returned would reflect the server name and port on which the connection from the proxy server was received, rather than the server name and port to whom the client directed the original request. Apache Tomcat 7 Version 7. Links Docs Home Config Ref. The native connectors supported with this Tomcat release are: JK 1. See the JK docs for details.
Other native connectors supporting AJP may work, but are no longer supported. Common Attributes. All implementations of Connector support the following attributes: Attribute Description ajpFlush.
Standard Implementations. To use AJP, you must specify the protocol attribute see above. Attribute Description acceptCount. These attributes are: javax. Note that this principal will have no roles associated with it. Java TCP socket attributes. Attribute Description socket. This is equivalent to standard attribute connectionTimeout. NIO specific configuration. The following attributes are specific to the NIO connector. Attribute Description pollTime. Active 2 years, 5 months ago. Viewed 55k times.

AJP is used mainly because: it's more performant than any HTTP exchange, it's integrated with broadly used reverse-proxying modules i. Paolo Maresca Paolo Maresca 6, 4 4 gold badges 31 31 silver badges 29 29 bronze badges. These days, these two products have roughly reached feature-parity, so momentum is really the only thing keeping AJP in high-usage.
First link doesn't work anymore. The administrative console forms often contain sensitive data. Consider using an SSL connection to protect it. WASCE 2.
