XiunoBBS 只需要一条规则：

将 *.htm* 转发到 index.php?*.htm* 即可。

Xiuno BBS 4.0  需要编辑 conf/conf.php

1. 编辑 'url_rewrite_on'=>1,

2. 清空 tmp 目录 

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 ~* \.(htm)$ {
    rewrite "^(.*)/(.+?).htm(.*?)$" $1/index.php?$2.htm$3 last;
}

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

# Apache 2.4
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^(.*?)([^/]*)$ $1index.php?$2 [QSA,PT,L]

# Apache other
#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 Rewrite.zip

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>
