super cace:

I also look at the footer at my page, it shows:

So I don’t know why teh wp-super-cache page is always 0. The following
is my rewrite rule. Does any body got a working rewrite rule for wp
suer cache? Thanks a lot.

            set $wp_super_cache_file '';
            set $wp_super_cache_uri $request_uri;

            if ( $request_method = POST )
            {
                    set $wp_super_cache_uri '';
            }

            if ( $query_string )
            {
                    set $wp_super_cache_uri '';
            }

            if ( $http_cookie ~*

“comment_author_|wordpress|wp-postpass_” )
{
set $wp_super_cache_uri ‘’;
}

            if ( $wp_super_cache_uri ~ ^(.+)$ )
            {
                    set $wp_super_cache_file

/wp-content/cache/wp_super_cache/$http_host/$1index.html;
}

            if ( -f $document_root$wp_super_cache_file )
            {
                    rewrite ^(.*)$ $wp_super_cache_file break;
            }

            if (-f $request_filename)
            {
                    expires 30d;
                    break;
            }

            if (!-e $request_filename)
            {
                    rewrite ^(.+)$ /index.php?q=$1 last;
