Apache 413 Request Entity Too Large

Today, the use of Web site configuration process, the site suddenly appeared 413 Request Entity Too Large error, the network checked the next Apache, are said to modify the PHP configuration error, but the site is Java, I give depressed. Then I took my boss and told me it was probably Apache and Tomcat connection configuration problem, Google keyword plus tomcat, and sure enough to check out (http://builddeploy.blogspot.com/2009/04/ resolving-http-error-413-request-entity.html), add Worker.web1.max_ to the Workers.properties configuration file that configures Apache and Tomcat load balancing packet_size=65536 and worker.web2.max_packet_size=65536, and then restart Apache, fix it.
