301重定向正则表达式优化需求：排除含/category/路径的页面不执行指定重定向

Got it, let's sort out this redirect issue for you. The problem with your current regex is that it doesn't account for paths that include /category/ before the /the-magazine/ segment—so it's matching both your target page and the category page you want to exclude.

Modified Regex Rule #

Here's the updated source URL regex that will skip any path containing /category/:

^(?!.*\/category\/)\/the-magazine\/2012-springsummer-issue\/([A-Za-z].*)

How It Works #

Let's break down the key additions:

• ^: Anchors the match to the start of the URL path, ensuring we check the entire path from the beginning.
• (?!.*\/category\/): This is a negative lookahead assertion. It tells the regex engine: "If the path contains /category/ anywhere, do NOT match this rule." The .* allows any characters before or after /category/, so it catches paths where /category/ is at the start (like your page 2) or anywhere else in the URL.
• The rest of the regex (\/the-magazine\/2012-springsummer-issue\/([A-Za-z].*)) stays the same—it still captures the trailing part of the URL to use in your target $1 variable.

Test It Out #

• For your page 1 (/the-magazine/2012-springsummer-issue/about-last-night-event-planning/): The path doesn't include /category/, so the regex matches, and it redirects to https://www.example.com/article/about-last-night-event-planning/ as intended.
• For your page 2 (/category/the-magazine/2012-springsummer-issue): The path has /category/, so the negative lookahead kicks in, and this rule won't apply—no unwanted redirect here.

Quick Note for Server Configs #

If you're using this in Apache (mod_rewrite) or Nginx, make sure your server supports PCRE (Perl Compatible Regular Expressions)—most modern servers do by default.

• For Apache, you might wrap this in a RewriteRule (note Apache strips the leading / from the path, so we remove it from the regex):

  RewriteRule ^(?!.*\/category\/)the-magazine\/2012-springsummer-issue\/([A-Za-z].*) https://www.example.com/article/$1 [R=301,L]
  

• For Nginx, the syntax would look something like:

  rewrite ^(?!.*\/category\/)\/the-magazine\/2012-springsummer-issue\/([A-Za-z].*) https://www.example.com/article/$1 permanent;
