Do note that on newer Apache versions the RewriteLog and RewriteLogLevel have been removed, and in fact will now trigger an error when trying to start Apache (at least on my XAMPP installation with Apache 2.4.2):
AH00526: Syntax error on line xx of path/to/config/file.conf: Invalid command 'RewriteLog', perhaps misspelled or defined by a module not included in the server configuration`
Instead, you're now supposed to use the general LogLevel directive, with a level of trace1 up to trace8. 'debug' didn't display any rewrite messages in the log for me.
Edit: note that this answer is 10+ years old. For newer versions of Apache, please see the answer by sp00n. Leaving this answer for users of older versions of apache.
For older version Apache:
For debugging mod_rewrite issues, you'll want to use RewriteLogLevel and RewriteLog:

请注意，在较新的 Apache 版本上，
RewriteLog和RewriteLogLevel已被删除，事实上现在在尝试启动 Apache 时会触发错误（至少在我的 XAMPP 安装中）阿帕奇2.4.2）：相反，您现在应该使用通用
LogLevel指令，级别为trace1< /code> 到trace8。 “调试”没有在日志中为我显示任何重写消息。示例：
LogLevel warn rewrite:trace3对于官方文档，
当然这也意味着现在你的重写日志将被写入通用错误日志文件中，你必须自己整理它们。

Of course this also means that now your rewrite logs will be written in the general error log file and you'll have to sort them out yourself.
编辑：请注意，这个答案已经有 10 多年历史了。对于较新版本的 Apache，请参阅 sp00n 的回答。将此答案留给旧版本 apache 的用户。
