nginx url rewrites for php-urls

Question

i have to permament redirect some old urls in nginx. the old urls are old-style php urls including a parameter for loading content. they look like this:

http://www.foo.com/index.php?site=foo http://www.foo.com/index.php?site=bar 

i want to redirect them to other urls like:

http://www.foo.com/news http://www.foo.com/gallery 

any advice on how i can achieve this? my tries failed. thanks in advance!

Answer 1

If you have a direct mapping between old URL parameters and new URL path, you could use such a syntax :

location /index.php { ... try_files $uri /$arg_site =404; } 

With such a config, any request starting with/index.php will first be tried againt the exact URL, then if there's no matching file or location, nginx will try an internal redirect with /foo if the original URL is /index.php?site=foo. If that fails too, nginx will send a 404 HTTP Not Found response.

The variable $arg_site is set to the value of the URL parameter site.

Answer 2

i fixed this issue by using php and not the nginx rewrite functionality:

if (isset($_GET["site"]) { switch ($_GET["site"]) { case 'foo': Header( "HTTP/1.1 301 Moved Permanently" ); Header( "Location: /foo" ); break; ... } }
