第二：创建一个xml文件；
比如您可以用 vbburlhack.xml ，在这个文件内贴上如下内容；
<?xml version="1.0" encoding="UTF-8"?>

第三：从vbb后台登录，点击产品，然后导入这个vbburlhack.xml 文件；
只要导入，就能成功了。效果可参见 http://www.linuxsir.org/bbs
注意：如果出现错误，就是你的.htaccess 没放对地方，或者权限不对。如果有问题，不要来问我，这个插件不是我写的，是洋人写的，我只是搬过来应用。呵。。。。出问题就去找他们吧。谢谢了~~~~
2.2 drupal 的URL地址重写设置；
drupal就比较简单了，不象vbb一样，要自己来弄，drupal程序本身就提供了.htaccess 文件。在安装程序的目录里就有。我们只是设置一下就能用了。要通过管理员帐号登录。如果您安装的了中文模块的支持，就是定义干净的URL，他要我们来测试是否能用。如果测试通过，打开就是了。只是点鼠标。如果你没有通过，说明你把.htaccess 文件给丢了，下载一份drupal，把这个文件复制过去就行了。注意是.htaccess ，前面有个小点……
3、关于本文；
本文是在维护 LinuxSir.Org 服务器的过程中，想到Clean URL是比较重要的， 因为这样Google就可以更加有效率的收录网页了。我们可以利用Google的搜索找到我们所需要的东西。在一定程度上，缓解了 LinuxSir.Org 服务器的压力。我们把搜索、邮局让Google来托管，可以减轻我们维护服务器的工作量，感谢Google！
