Apache (internal dummy connection)

Today i checked my apache log file in my server and  found lot of  "internal dummy connection". That is like below

          [root@server ~]# cat /var/log/httpd/access_log

 - - [21/Oct/2013:23:21:14 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:22:21 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:22:49 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:23:51 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:24:53 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:25:10 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:32:32 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:32:34 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:34:05 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:34:06 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"
 - - [21/Oct/2013:23:34:32 +0530] "OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)"

I want to ignore above log from access.log file . So i searched and found solution for "internal dummy connection"

Solution :

    I added below lines in "httpd.conf" file

             [root@server ~]# vim /etc/httpd/conf/httpd.conf

                          SetEnvIf Remote_Addr "127\.0\.0\.1" loopback

                          SetEnvIf Remote_Addr "::1" loopback

                          SetEnvIf User-Agent ".*internal dummy connection.*" loopback

                          CustomLog logs/access_log combined env=!loopback

              :wq

     After i restarted  the httpd service

            [root@server ~]# /etc/init.d/httpd restart

My issue resolved.....
