Apache Tomcat (called 'Tomcat' for short) is an open-source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and WebSocket technologies. Tomcat provides a 'pure Java' HTTP web server environment in which Java code can run. (int)Tomcat will cache SocketProcessor objects to reduce garbage collection. The integer value specifies how many objects to keep in the cache at most. The default is 500. Other values are -1 for unlimited cache and 0 for no cache. Socket.keyCache (int)Tomcat will cache KeyAttachment objects to reduce garbage collection. Happy Holidays from TOMCAT and JTE. Staging, Lighting and Support Systems.
