开了会话认证挺吃CPU，而且一般CC攻击软件都有跟踪302重定向功能，所以不建议开启
302这个对于一些特殊CC防护很不错，例如discuz随机URL CC攻击，把你的每个帖子都打一遍。但是对于同URL攻击是完全没有多大效果的。
kangle web server的话里面叫做http redirect，就和这个会话认证差不多，一般情况下开启html redirect防御模式就好了。
DDOS Firewall后台通过输入如下访问，具体参数设置不举例，可以防小流量DDOS攻击和常见CC攻击，不过还是建议使用完美无误封的kangle商业版：http://bbs.itzmx.com/thread-7047-1-1.html
