重定向和伪静态知识点总结

- 伪静态是相对真实静态来讲的，
- 伪静态只是改变了URL的表现形式,实际上还是动态页面
- 伪静态有了真静态一样的SEO什么是伪静态和重定向？

- 通过各种方法将各种网络请求重新定个方向转到其它位置(分为内部和外部)
- http标准协议中的3xx ( 主要用302 , 303 )
- 用重定向技术来实现伪静态.htaccess性能问题

- I/O消耗
- 开启后访问页面,要查找所有.上级的目录中的.htaccess文件
- 可以被主配置文件替代mod_rewrite简介

- Apache的URL操作模块
- 包含RewriteBase RewriteRule、 RewriteCond、RewriteMapLogLevel操作示范

- 设置LogLevel alert rewrite:trace8 ( 1~8 )生产模式不要大于trace2
- 查看apache\_ error.log日志文件
- 只能在conf文件中设置,不能在.htaccessRewriteRule语法说明

- RewriteRule模式匹配替换的URL [flags]
- 模式匹配支持Perl格式的正则表达式、和rewrite的变量
- 替换的URL支持模式匹配的结果和rewrite变量
- 多个flag用逗号隔开[R= 302,C]实现伪静态SEO的实践方法实现防盗链、限制迅雷、文件访问控制等的重定向常规应用实现动态镜像、集群网站、负载均衡等重定向高级应用
1、RewriteRule flag 参数说明R=301永久 有利于seo  评分给新地址R=302临时 默认302 重定向  给新地址新的评分 seo作弊
