Memcached not used for SSI's

[Hone Watson]

I am trying a SSI set up but it seems that nginx is not using
memcached for the partials.

If I place the url for the partials in the directory nginx will use memcached.

For the SSI includes it does not use memcached but redirects to php?

location /dssi/ {

	set  $memcached_key  $host$request_uri;
	memcached_pass   127.0.0.1:11244;
	default_type       text/html;

	error_page       404 = /partial_index.php?q=$uri;
}

location ~ /partial_index\.php$ {

	fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
	fastcgi_param  SCRIPT_FILENAME /home/testing/public_html$fastcgi_script_name;
	include        /usr/local/nginx/conf/fastcgi_params;

}
