.htaccess重定向，无重定向循环

我肯定在那里有一个答案，但是它确实让我耳目一新，并且我讨厌与.htaccess重定向有关的任何事情.

Im sure there is an answer out there for this somewhere but its doing my head in and I hate anything to do with .htaccess redirects.

基本上我正在尝试这样做

Basically I am trying to do this

RewriteRule /about/(.*) www.domain/example/about/$1 [R=301,L].

问题在于，这导致重定向循环，因为从URL重定向到URL都包含"about".

Problem is that this results in a redirect loop because "about" is in both the redirected from and redirected to url.

id想要做的是拥有它，以便仅当根URL在/about/之前时才重定向.我确实尝试过这样做:

What id like to do is have it so that it will only redirect if the root url is before the /about/. I did try doing this with this:

RewriteRule www.domain/about/(.*) www.domain/example/about/$1 [R=301,L].

但是那没用.

有人对此有直接解决方案吗?

Does anyone have a straight forward solution for this.

谢谢

推荐答案

此规则应使用正则表达式模式中的锚点:

This rule should work with anchors in regex pattern:

RewriteRule ^/?(about/.*)$ /example/$1 [R=301,L,NC]

^/?about仅匹配www.domain/about/，而不匹配www.domain/example/about/
