nginx: How to mass permanent redirect from a given list?

Question

I have about 400 url that will change in the new version and for some reasons I can't repeat the same type of url structure in the new website.

My question is, can I give a url list to nginx (yeah I know the 400 ones), and tell him simply that each one of them are going to another url?

Like I said the url structure will be different so I can't use any type of pattern.

Thanks in advance.

If you have a very long list of entries, could be a good idea to keep them outside of the nginx configuration file:

map_hash_bucket_size 256; # see http://nginx.org/en/docs/hash.html  map $request_uri $new_uri {     include /etc/nginx/oldnew.map; #or any file readable by nginx }  server {     listen       80;     server_name  your_server_name;      if ($new_uri) {        return 301 $new_uri;     }      ...     } 

/etc/nginx/oldnew.map sample:

/my-old-url /my-new-url; /old.html /new.html; 

Be sure to end each line with a ";" char!

Moreover, if you need to redirect all URLs to another host, you could use:

return 301 http://example.org$new_uri; 

Or, if you also need to redirect to another port:

return 301 http://example.org:8080$new_uri;
