虽然压力测试，所有请求只去1节点
问题描述：
好心我需要有人来帮助我在我面临的奇怪问题。 我在Jboss eap 6上部署了一个Web应用程序。 我在同一台计算机（服务器1 - 服务器2）上配置了两个JBoss节点，并将它们配置为集群环境。 我也配置Apache mod_cluster作为负载平衡器。 当我试图通过调用我的应用程序的不同机器测试环境时，一切工作正常，两个节点一起工作，负载均匀分布在两个节点上。 开始使用microsoft visual studio 2012 web加载时出现问题，它模拟对应用程序的并发请求。我注意到所有请求都由1个节点接收，而其他节点保持空闲！ 我尝试了一些故障排除像两个节点编辑独立，ha.xml和编辑以下行虽然压力测试，所有请求只去1节点

最后我解决了我的问题，事实证明，当记录微软负载测试中的测试场景时，它将jsessionid添加到URL中，由于所有请求都具有相同的sessionid，导致了问题。 解决方案是从测试网址中删除此参数:)
