Question

I use (File System Based) static html files for caching, for some reasons i don like this. I want store cache files (html, images) in database.

Now it work like that:

if nginx can get cache:
    return cache to user
else
    proxy_pass request to backend server

It looks like this in my Nginx config file

if (-f $cache_dir_prefix/$query) {
    rewrite (.*) $query break;
}

if (!-f $cache_dir_prefix/$query) {
    proxy_pass http://lionyzer;
    break;
}

It’s posible to do IF check with GridFS Or Amazon S3 or Mysql or anything alse?

Thanks alot

    fastcgi_param SCRIPT_FILENAME scaleme.php;

You can use the nginx-gridfs module to serve GridFS files directly from Nginx, and then catch a 404 for files not found and proxy those to the other server.
