Nginx：

打开 nginx 配置文件 /usr/local/nginx/conf/nginx.conf 找到对应的虚拟主机配置处，追加加粗行:

location / {
    rewrite "^(.*)/(.+?).htm(.*?)$" $1/index.php?$2.htm$3 last;
    index    index.html index.htm index.php;
     root     /data/wwwroot/xiuno.com;
}

然后重新启动 nginx: service nginx restart

Apache:
vim /etc/httpd/conf/httpd.conf

<Directory d:/xiuno.com>
    Options FollowSymLinks ExecCGI Indexes
    AllowOverride all
    Order deny,allow
    Allow from all
    Satisfy all
</Directory>

NameVirtualHost *:80

Apache .htaccess

如果Appache 支持 .htaccess，那么可以编辑 .htaccess 文件放置于根目录下：

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^(.*?)([^/]*)\.htm(.*)$ $1/index.php?$2.htm$3 [L]
</IfModule>

Apache httpd.conf

如果将规则直接放入 httpd.conf 则需要在前面加 / ，看来 Apache 也反人类：

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^(.*?)([^/]*)\.htm(.*)$ $1/index.php?$2.htm$3 [L]
</IfModule>

SAE环境，根目录建立 config.yaml 文件：

appname: axiuno
version: 1
handle:

- rewrite: if ( !is_dir() && !is_file() && path ~ "admin/(.*.htm)" ) goto "admin/index.php?%1"
- rewrite: if ( !is_dir() && !is_file() && path ~ "[^/?].htm" ) goto "index.php?%1"

IIS:
1. 下载附件
2. 解压到 c:\Rewrite
3. 在IIS的Isapi上添加这个筛选器, 筛选器名称Rewrite,可执行文件选择 Rewrite.dll
4. 重新启动IIS
5. httpd.ini 是配置文件,如果您了解Rewrite 规则,可以直接对其进行编辑，以下为包内设置好的Xiuno BBS的规则：
[ISAPI_Rewrite]

# 3600 = 1 hour
CacheClockRate 3600
RepeatLimit 32
#RewriteRule .*\.(?:gif|jpg|png|css|js|txt|jpeg|swf|flv) $0 [I,L]
#RewriteRule /httpd(?:\.ini|\.parse\.errors) / [F,I,O]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/admin(.*)\.htm(.*) /admin/index.php?$1.htm$2 [L]
RewriteRule ^(.*)\.htm(.*) /index.php?$1.htm$2 [L]

另外一种 IIS Rewrite：
[ISAPI_Rewrite]
# 3600 = 1 hour
CacheClockRate 3600
RepeatLimit 32
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/admin/(.*)\.htm(.*) /admin/$1.htm$2 [L]
RewriteRule ^(.*)\.htm(.*)$ /$1.htm$2 [L]

如果要放到目录下，比如 bbs 目录，在 rewrite 规则前面加上目录即可，比如 apache .htaccess：
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^bbs/admin/(.*)\.htm(.*)$ /admin/index.php?$1.htm$2 [L]
RewriteRule ^bbs/(.*)\.htm(.*)$ /index.php?$1.htm$2 [L]
</IfModule>

IIS 的高版本配置方法：
Xiuno3 IIS7,IIS7.5伪静态规则,懒人版

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="xiuno3">
<match url="^((.*)/)?(.+).htm$" />
<action type="Rewrite" url="{R:1}\index.php?{R:2}.htm" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

IIS Rewrite 支持 Apache .htaccess ：
反人类的 IIS REWRITE！！！
