I have a haproxy 1.9.4 running on CentOS 7 machine with the following configuration

backend test
   acl is_cached path_end .js .css
   http-request cache-use static if is_cached
   http-response cache-store static if is_cached
   server my_webserver 127.0.0.1 check
cache static
    total-max-size 512
    max-age 300s

So is there way to purge cache without restarting haproxy?

How can I view cache?

I have a static IP configuration on my CentOs 7 network interface, configured 3 DNS servers, first two with public, third one with private IP address, but third one doesn't appear at /etc/resolve.conf. Here is my interface config file.

I have the following configuration for my wp site which is running on nginx 1.8.1 location ^~ /wp-login.php { allow 10.0.0.0/24; deny all; }

location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
}

When I opening http://example.com/wp-login.php from my LAN, it downloads php file instead of passing it to fastcgi. After that I added all fastcgi lines inside of wp-login.php location and it began to work.

location ^~ /wp-login.php {
        allow 10.0.0.0/24;
        deny all;
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}

But is that the only way? Can I make a ordering of passing specific pattern on nginx?

Thanks beforehand.

I want to forward incoming multicast traffic to other multicast address listened on my server interface. My machine running on Ubuntu 14.04. Have a incoming traffic on 239.0.0.1 udp port 1001, want to forward to 224.0.0.1. I wrote the following rule. iptables -t nat -I PREROUTING 1 -m pkttype --pkt-type multicast -d 239.0.0.1/32 -p udp --dport 1001 -j DNAT --to-destination 224.0.0.1:1001 But there is no any traffic matching it, root@serv:/root# iptables -t nat -L -nv --line Chain PREROUTING (policy ACCEPT 3 packets, 180 bytes) num pkts bytes target prot opt in out source destination 1 0 0 DNAT udp -- * * 0.0.0.0/0 239.0.0.1 PKTTYPE = multicast udp dpt:1001 to:224.0.0.1:1001 also when I listening my p3p1 inteface with tcpdump there is show that there is incoming traffic to 239.0.0.1.
