This is .htaccess on Nginx ?

PHP Code:

# Modified gzip settings: added CSS/JS,
# but completely disabled for broken browsers.
gzip_types       text/plain text/css application/x-javascript text/xml text/javascript;
gzip_disable     "MSIE [1-6].(?!.*SV1)";


# globally disable external access to attachments, but enable for X-Accel-Redirect
location /uploads {
    internal;
}
# enable thumbnails direct access, but nothing else!
location ~* /uploads/(.*)\.thumb$ {
    expires 24h;
}


# Expires for static files.
location /images/ {
    expires 24h;
}
location /clientscript/ {
    expires 24h;
}
location /custom { # All at once: profile pics, avatars, group images
    expires 24h;
} 


And about " path to attachments "
is full path like : /home/www/html/sites.com/attachment
or
just /attachment/
