使用.htaccess重定向404内容的规则

Question

It's quite common for us to put in progress sites at www.domain.com/dev/ and then once the client has signed off the site to move it to the top level www.domain.com, what we like is to be able to put a .htaccess file in the top level so that once we've moved the site out of /dev if the client accidently goes to www.domain.com/dev/apage.php that they be redirected to www.domain.com/apage.php, but only if www.domain.com/dev/apage.php doesn't exist.

Sometimes the dev folder will be called various other things, and ideally we don't want to have to edit the .htaccess file to match the folder name.

Thanks for any help.

You could do something like

Edited based on comments:

RewriteEngine On

RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule dev/(.*)$ $1 [R=301,L]

Which basically means that if the file doesn't exist - RewriteCond %{REQUEST_FILENAME} !-f - then rewrite any request to dev back to the root. You have to specify dev/ in the rewrite rule as otherwise you will get stuck in a redirect loop.

This will only work however if you are using explicit files rather than a framework with everything routed through index.php for example
