if requested file doesn't exist in a/b/c.jpg to search in /old/a/b/c.jpg

  • 772

I'm using apache 2.2 and that serves a website that some of it's content moved to different directories. is there a way to had some kind of a rewrite rule to .htacces file if the requested file (doesn't matter if it's php or jpg or anything else) doesn't exist, to prepend a directory name and to try again ?

for example:

if the request URL is a/b/c.jpg and it doesn't exist,

to try to search for it in /old/a/b/c.jpg.

thanks!

  1. I think you can do it with -f (check if file exists). Try something like this (untested):

    RewriteEngine on
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} ! -f
RewriteRule ^(.*)$ /old/$1 [L,R=301]

    Edit: fixed typo.

  2. RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/old/
RewriteRule ^(.*)$ /old/$1 [L,QSA]

    I think it is also needed to check directories. And add the last RewriteCond to avoid recursive rewrites.
