fastcgi_cache

[ariel_esp]

Hi,
I am trying setup fastcgi_cache.
Working fine.... BUT I need bypass some pages... when theses pages have
header "no-cache".... but I dont know how to do this...
The rules for bypass using urls, work fine.. like this:

[code]
if ($request_uri ~*
"(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)")
{
        set $cache_uri 'null cache';
    }
[/code]

How can I bypass cache setting header page "no-cache" ?
Example, in varnish work fine:
 if (req.http.Cache-Control ~ "no-cache")
{
    return (pipe);
}

thanks
