虽然我已经看到了这个塞马几个帖子，我仍然有一些问题，以达到我想要的。 我的旧网址的人，如：

Although I already saw few posts about this thema, I am still having some problems to achieve what I want. My old URL's were like:

myhostname/offer/1234_Nice_Offer_Cool_Whatever_HEllyeah.htm

和很明显，我想将它们改写为：

And obviously I want to rewrite them to:

myhostname/offer/1234-nice-offer-cool-whatever-hellyeah.htm

这是在code我尝试在.htaccess。这工作正常，以取代在URL的下划线，他们没有任何的目录：

This is the code I tried in .htaccess. This works fine to replace the underscores in URL's which they don't have ANY directory:

RewriteCond %{REQUEST_URI} \.htm$ [NC] RewriteRule ^([^_]*)_+(.*)$ $1-$2 [E=underscores:Yes,N] RewriteCond %{ENV:underscores} ^Yes$ RewriteRule ^(.*)$ %{HTTP_HOST}/$1 [R=301,L]

所以，这PAIRE规则正常工作与网址，如：

So, this paire of rules work fine with URL's like:

myhostname/1234_Some_Section_hellyeah.htm

但是当我尝试在同一$ C $下的URL，如：

But when I try the same code for URL's like:

myhostname/dir1/dir2/dir3/1234_Some_Offer_Or_Section.htm

然后，服务器使一个无限循环（[N]标志的我的身影......） 基本上，我想知道以何种方式影响每个目录的URL规则，为什么我会收到这个无限循环。谢谢！

Then, the server makes an infinite loop (I figure of the [N] flag...) Basically, I would like to know in which way affects a per-directory URL to these rules and why am I getting this infinite loop. Thanks!

推荐答案

您不必N标记。要通过连字符代替下划线递归以下code将工作：

You don't need N flag. To replace underscore by hyphen recursively following code will work:

RewriteRule ^([^_]+)_(.+?\.htm)$ $1-$2 [L,NC,E=underscores:Yes] RewriteCond %{ENV:REDIRECT_underscores} ^Yes$ RewriteRule ^([^_]+)$ /$1 [R=301,L]
