Question

I have an application that I have rewritten with rails. Old application is in php.

I need to redirect all php requests to a subdomain old.example.com (I have put my old application to run there) so that the old links would still work. I believe all of the links have a “.php” in them and none of my new urls have that. So it could be used as a condition for redirecting.

I have planned to use apache RedirectMatch. So something like:

RedirectMatch \.php http://old.example.com

should be close. I believe. I just don’t know how to pass the request path to the redirect rule.

Or if someone has a better idea how to do this?

Using Apache mod rewrite, you would use the following:

RewriteEngine On
RewriteBase /
RewriteRule ^.*\.php.*$ http://old.example.com/index.php [R=301,NC]

If you want to actually insert the page they were trying to reach in the redirect URL:

RewriteEngine On
RewriteBase /
RewriteRule ^/?(.*)\.php.*$ http://old.example.com/$1.php [R=301,NC]

$1 will insert anything that matches the regular expression in the parentheses.

For GET parameters:

RewriteEngine On
RewriteBase /
RewriteRule ^/?(.*)\.php(.*)$ http://old.example.com/$1.php$2 [R=301,NC]
