Apache rewrite in Nginx format

Server NGINX
1

Hi,

Is it possible to express the following Apache rewrite rule in Nginx?

 RewriteCond %{QUERY_STRING} !^nobranding$
 RewriteCond %{REQUEST_FILENAME} ^/assets/XL/([^.]+)\.([jpegif]+)$
 RewriteCond /usr/local/www/assets-nz/XL/%1.branded.%2 -f
 RewriteRule ^/([^.]+)\.([jpeg]+)$ /$1.branded.$2

In Nginx, this would be in a location block with an alias, so

location /assets {
alias /usr/local/www/assets-nz/;

 ... rewrites go here ...

}

But, I understand you can’t rewrite with an alias present? So how can
I implement the above Apache rewrite?

Cheers

Phil Murray

Try

location /assets {

  if ($args = nobranding) {
      rewrite  ^(.+)$ /nobranding$1  last;
  }

  rewrite  ^/assets/XL/(.+)\.(jpeg|jpg|gif)  /XL/$1.branded.$2;
  root /usr/local/www/assets-nz;
  error_page  404  =  /nobranding/assets$uri;

}

location /nobranding/assets {
internal;
alias /usr/local/www/assets-nz/;
}

Thanks Igor, that works… but to throw a spanner into the works, I
have at the end of this configuration:

location / {
root /path/to/rails/public/

… lots of rewrites for fixing up old URLs

if (!-f $request_filename) {
proxy_pass http://mongrel;
break;
}
}

And the !-f/proxy_pass seems to pick up the request in the case where
blah.branded.jpeg doesn’t exist (and should just serve blah.jpeg
instead), and thus passing it through to mongrel.

Is there a way to force the /nobranding/assets location to be used.
Do rewrites alter $uri ?
