is it possible to write a mod_rewrite rule, which reroutes requests to
another server, if they are not found on the current server e.g.:
Requested URL:
www.foo.com/home.php
Backup URL:
www.bar.com/home.php
The redirect should only be made if the Requested URL delivers a 404
message.
You can do what you want using mod_rewrite:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/(.*) http://www.bar.com/$1 [R,L]
See https://httpd.apache.org/docs/2.2/rewrite/ for information on how to
use mod_rewrite.
Alternatively, you could set up an ErrorDocument on your server to
handle all 404 errors. Have this ErrorDocument be a script that gets
the URI path the user was trying to access from the REDIRECT_*
environment variables and then prints HTTP response headers to redirect
the user to the appropriate URL for www.bar.com. For details, see
https://httpd.apache.org/docs/2.2/custom-error.html
