    ▪通过例子来看nginx下的Rewrite规则      Apache下的Rewrite规则是详细的规则，nginx下的中文文档好像没有看到，这里有个英文的文档：http://wiki.nginx.org/NginxHttpRewriteModule 。 Apache下的Rewrite规则基本上到nginx下，也可以直接使用，不行的.........

    ▪老生常谈-nginx配置文件的rewrite中break和last的区别      Nginx配置文件的rewrite中break和last的区别，有需要的朋友不妨参考下。 来看一个这样的server配置：   代码如下: server {  listen       80;  server_name  www.; root         /var/www/xxx;  index.........

    ▪nginx1.0.0配置ngx_cache_purge实现高效反向代理的方法      nginx1.0.0配置ngx_cache_purge实现高效反向代理的方法，有需要的朋友可以参考下。 nginx默认安装会带有反向代理的功能，但想要更好的使用，还得配备frickle.com的ngx_cache_purge模块，用于清除指定URL.........

代码如下:

if ($http_user_agent ~ MSIE) {
  rewrite  ^(.*)$  /msie/$1  break;
}

代码如下:

if ($host != 'www.' ) {
rewrite ^/(.*)$ http://www./$1 permanent;
}
 

代码如下:

location ~* .(gif|jpg|png|swf|flv)$ {
valid_referers none blocked itlearner.com;
if ($invalid_referer) {
return 403;
}
}
 

代码如下:

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;
}
}
 

代码如下:

    if (!-e $request_filename) {
      rewrite ^/post/([0-9]+)/?([0-9]+)?/?([0-9]+)?/?$ /read.php?entryid=$1&page=$2&part=$3 last;
      rewrite ^/page/([0-9]+)/([0-9]+)/?$ /index.php?mode=$1&page=$2 last;
      rewrite ^/starred/([0-9]+)/?([0-9]+)?/?$ /star.php?mode=$1&page=$2 last;
      rewrite ^/category/([^/]+)/?([0-9]+)?/?([0-9]+)?/?$ /index.php?go=category_$1&mode=$2&page=$3 last;
      rewrite ^/archiver/([0-9]+)/([0-9]+)/?([0-9]+)?/?([0-9]+)?/?$ /index.php?go=archive&cm=$1&cy=$2&mode=$3&page=$4 last;
      rewrite ^/date/([0-9]+)/([0-9]+)/([0-9]+)/?([0-9]+)?/?([0-9]+)?/?$ /index.php?go=showday_$1-$2-$3&mode=$4&page=$5 last;
      rewrite ^/user/([0-9]+)/?$ /view.php?go=user_$1 last;
      rewrite ^/tags/([^/]+)/?([0-9]+)?/?([0-9]+)?/?$ /tag.php?tag=$1&mode=$2&page=$3 last;
      rewrite ^/component/id/([0-9]+)/?$ /page.php?pageid=$1 last;
      rewrite ^/component/([^/]+)/?$ /page.php?pagealias=$1 last;

      #Force redirection for old rules

      rewrite ^/showday\_([0-9]+)\_([0-9]+)\_([0-9]+)\.htm$ http://$host/date/$1/$2/$3/ permanent;
      rewrite ^/showday\_([0-9]+)\_([0-9]+)\_([0-9]+)\_([0-9]+)\_([0-9]+)\.htm$ http://$host/date/$1/$2/$3/$4/$5/ permanent;

      #Filename alias
      rewrite ^/([a-zA-Z0-9_-]+)/?([0-9]+)?/?([0-9]+)?/?$ /read.php?blogalias=$1&page=$2&part=$3 last;
    }

代码如下:

server { 
listen       80; 
server_name  www.;
root         /var/www/xxx; 
index        index.php index.html index.htm; 
location [loc-1] { 
/**此处略去1000字**/ 
} 
location [loc-2] { 
/**此处略去1000字**/ 
} 
rewrite [match-1] [replace-1] break; 
rewrite [match-2] [replace-2] last; 
rewrite [match-3] [replace-3] last; 
rewrite [match-4] [replace-4] break;  
}

代码如下:

/---------------------------下边是算法---------------------------/
amt = int[4]
for(i=1 to 4){
if(match[i].tag=='break')amt[i]=10;
else amt[i]=1;
}

while(还没有匹配过 OR 上一轮有匹配成功){
for i=1 to 4{
if(amt[i]==-1)continue;
if(url 匹配 match[i]){
url = do_replace(replace[i]);
amt[i]--;
} else {
amt[i]==-1
}

if(url 匹配 Loc[i]) 完成
}
}

if(url 在硬盘物理存在) 完成
else echo 错误404

代码如下:

wget http://labs.frickle.com/files/ngx_cache_purge-1.3.tar.gz
