nginx rewite 規則，官方文檔：http://wiki.nginx.org/NginxHttpRewriteModule
nginx rewrite規則格式：rewrite regex replacement flag
flag標記有四種格式：
last – 相當于Apache中的L break – 中止Rewirte，不在繼續匹配 redirect – 返回臨時重定向的HTTP狀態302，相當于Apache中的R permanent – 返回永久重定向的HTTP狀態301，相當于Apache中的R=301
可以放在server, location 和 if 模塊中。
匹配判斷：
~ 為區分大小寫匹配; !~為區分大小寫不匹配
~* 為不區分大小寫匹配；!~為不區分大小寫不匹配
例如，設定nginx在用戶使用ie的使用重定向到/nginx-ie目錄下：
if ($http_user_agent ~ MSIE) {
rewrite ^(.*)$ /msie/$1 break;
}
附，常用nginx Rewrite 規則配置代碼。
1、只使用一個網址，比如主力網址設為www.shinetop.cn。
if ($host != 'www.shinetop.cn' ) { rewrite ^/(.*)$ http://www.shinetop.cn/$1 permanent; }
訪問35.com時，會自動跳轉到www.shinetop.cn。
2、防盜鏈
location ~* .(gif|jpg|png|swf|flv)$ {
valid_referers none blocked 35.com dgjs123.com;
if ($invalid_referer) {
return 403;
}
}
盜鏈時則返回403錯誤，允許的域名可以直接跟在第二行的域名后面。
3、WordPress的Rewrite
location / {
index index.html index.php;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
rewrite (.*) /index.php;
}
}
目前，代碼收藏上就是使用的這段代碼。
