spartacus. on "[Plugin: WP Super Cache] Website doesn't display when cache is on"

Hi Donncha,

these are the errors i get when the plugin is on: (i changed the ip and domain)

2012/08/09 15:07:49 [error] 3387#0: *488543 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 124.43.132.12, server: mydomain.com, request: "POST /wp-admin/admin-ajax.php HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-fpm.sock:", host: "www.mydomain.com", referrer: "http://www.mydomain.com/path-to-page/"

2012/08/09 15:10:50 [error] 3384#0: *492364 readv() failed (104: Connection reset by peer) while reading upstream, client: 124.43.132.12, server: mydomain.com, request: "GET /stories/story-title/ HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-fpm.sock:", host: "www.mydomain.com"

is there any nginx/multisite configuration you recommend using with your plugin?
are you going to update the plugin to full support nginx? (in the cache options there's only apache mod_rewrite, php and legacy)

thanks in advance for your help.
