How to flush cache without reloading nginx?

Question

PHP

I cached blogs on WordPress like this:

user www-data;
worker_processes  2;

error_log  /web/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /web/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  650;
    server_tokens off;
    client_max_body_size 80m;
    #client_body_buffer_size 128k;
    charset utf-8;
    gzip_types text/plain application/xml application/x-javascript text/javascript text/css text/json;
    gzip  on;
    server_names_hash_bucket_size 64;

    proxy_cache_path /var/cache/pages levels=1:2 keys_zone=czone:4m max_size=50m inactive=120m;
    fastcgi_cache_path /var/cache/fpm levels=1:2 keys_zone=fcgi:100m;
    fastcgi_cache_key "$scheme$request_method$host$request_uri";

    include /etc/nginx/sites-enabled/*;
    include /etc/nginx/conf.d/*.conf;
}

server
{
    server_name site.ru www.site.ru;
 
    access_log /web/log/nginx/site.ru.access.log;
    error_log /web/log/nginx/site.ru.error.log;
    root /web/site.ru;
 
    index index.php index.html index.htm;
 
    # enforce www (exclude certain subdomains)
    #if ($host !~* ^(www|subdomain))
    #{
    #   rewrite ^/(.*)$ $scheme://www.$host/$1 permanent;
    #}
 
    # enforce NO www
    if ($host ~* ^www\.(.*))
    {
        set $host_without_www $1;
        rewrite ^/(.*)$ $scheme://$host_without_www/$1 permanent;
    }
 
    # unless the request is for a valid file, send to bootstrap
    if (!-e $request_filename)
    {
        rewrite ^(.+)$ /index.php?q=$1 last;
    }
 
    # catch all
    error_page 404 /index.php;
 
    # use fastcgi for all php files
    location ~ .(php|html)$
    {
        #fastcgi_pass 127.0.0.1:9000;
        # With php5-fpm:
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_cache fcgi;
        fastcgi_cache_valid 200 60m;
        fastcgi_pass_header "X-Accel-Redirect";
        fastcgi_pass_header "X-Accel-Expires";
    }
 
    # deny access to apache .htaccess files
    location ~ /\.ht
    {
        deny all;
    }
    location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|pdf|ppt|txt|bmp|rtf|js)$ {
        expires 10d;
    }    
}

is it possible to somehow mess up the reset of this whole thing without restarting nginx?
