为什么此mod_rewrite规则不起作用（通过.htaccess将一个特定的网址访问另一个）

Question

RewriteRule ^ / tag / term $ / tag / term-expanded-here [R]

Answer 1

If you're using mod_rewrite in a .htaccess file , you need to remove the path prefix from the pattern:

When using the rewrite engine in .htaccess files the per-directory prefix (which always is the same for a specific directory) is automatically removed for the pattern matching and automatically added after the substitution has been done.

In case of the .htaccess file in the document root directory it's the leading / :

RewriteRule ^tag/term$ /tag/term-expanded-here [R]
