How can I use an .htaccess redirect for a partial path?

Question

I had to adjust some paths on my site and I need to use .htaccess to redirect the items on the chance a user accesses the old url.

For example my old urls (relative)

You can use either mod+alias:

Redirect 301 /old-path /new-path

or using mod_rewrite:

RewriteEngine On
RewriteRule ^/?old-path/(.*)$ /new-path/$1 [L,R=301]

These could be in the htaccess file in your document root or in the server/vhost config. If you already have rewrite rules somewhere, you may just want to stick with mod_rewrite because redirecting with mod_alias while using mod_rewrite can sometimes give conflicting results.
