最近在用ecshop开发一个商城，源码中提供了通过 .htaccess来启动url重写。但是考虑到以后的性能和安全问题：
1、性能：如果AllowOverride启用了.htaccess文件，则Apache需要在每个目录中查找.htaccess文件，因此，无论是否真正用到，启用.htaccess都会导致性能的下降。另外，对每一个请求，都需要读取一次.htaccess文件。还有，Apache必须在所有上级的目录中查找.htaccess文件，以使所有有效的指令都起作用；即使这些文件都不存在。也会导致性能的下降。

2、安全：这样会允许用户自己修改服务器的配置，这可能会导致某些意想不到的修改，所以请认真考虑是否应当给予用户这样的特权。但是，如果给予用户较少的特权而不能满足其需要，则会带来额外的技术支持请求，所以，必须明确地告诉用户已经给予他们的权限，说明AllowOverride设置的值，并引导他们参阅相应的说明，以免日后生出许多麻烦。

我决定使用httpd 设置来启用url重写，关于ecshop的urlrewrite整理如下：
您可根据自己服务器的版本去修改httpd.conf或httpd-vhosts.conf
