问一个rewrite的问题

RewriteEngine On
        RewriteRul       (.*)    /web/$1


      我通过rewriteLog查询，发现并不是这句运行一次就结束。比如 请求/bbs.php  变成了/web/bbs.php  这个时候其实已经得到答案，但还会继续INTERNAL REDIRECT ,又开始了新一论的RewriteRule.这样显然进入死循环。

     1,是这么执行的吗?一定要自己来避免循环吗?还是可以什么地方配置.请大家说说看.
       2.我发现我的环境里 $1不包含 / 字符，这跟手册似乎不一样,你们呢。Server version: Apache/2.2.8 (Unix)

大家帮帮忙啊.

[L]

[L]  表示不执行下面的RewriteRule,现在后面没有了。要[L]干什么呢。而且实际上不行的.

请大家帮忙看看啊
