Nginx

1. 在 Apache 的写法

RewriteCond  %{HTTP_HOST}  nginx.org
RewriteRule  (.*)          http://www.nginx.org$1

在 Nginx 可以对应写成：

server {
    listen       80;
    server_name  www.nginx.org  nginx.org;
    if ($http_host = nginx.org) {
        rewrite  (.*)  http://www.nginx.org$1;
    }
    ...
}

但 Nginx 作者更建议的方法是：

server {
    listen       80;
    server_name  nginx.org;
    rewrite   ^  http://www.nginx.org$request_uri?;
}

server {
    listen       80;
    server_name  www.nginx.org;
    ...
}

2. 在 Mongrel的写法：

DocumentRoot /var/www/myapp.com/current/public

RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f
RewriteCond %{SCRIPT_FILENAME} !maintenance.html
RewriteRule ^.*$ %{DOCUMENT_ROOT}/system/maintenance.html [L]

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^(.*)$ $1 [QSA,L]

RewriteCond %{REQUEST_FILENAME}/index.html -f
RewriteRule ^(.*)$ $1/index.html [QSA,L]

RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^(.*)$ $1/index.html [QSA,L]

RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L]

在 Nginx可对应写成

location / {
    root       /var/www/myapp.com/current/public;

    try_files  /system/maintenance.html
               $uri  $uri/index.html $uri.html
               @mongrel;
}

location @mongrel {
    proxy_pass  http://mongrel;
}

这个就比Apache 的简化多了。
