How to stop my the logging of my IP address?

A Gbytes long log

/var/log/apache2/access_log

causes my question: How to stop my IP logging (just because of frequent AJAX/setTimeout).

As config:

SetEnvIf Remote_Addr "ip\.ip\.ip\.ip" dontlog
CustomLog /var/log/apache2/access_log common env=!dontlog

In

/etc/apache2/httpd.conf

Didn't work THEN those six guessing lines were added:

SetEnvIf Remote_Addr "ip\.ip\.ip\.ip" dontlog
SetEnvIf Remote_Addr "ip\.ip\.ip\.ip" nolog
SetEnvIf Remote_Addr "ip\.ip\.ip\.ip" no_log
SetEnvIf Remote_Addr "ip.ip.ip.ip" dontlog
SetEnvIf Remote_Addr "ip.ip.ip.ip" nolog
SetEnvIf Remote_Addr "ip.ip.ip.ip" no_log

and didn't work either!

tail /var/log/apache2/access_log

Is STILL the same:

ip.ip.ip.ip - - [13/Mar/2015:07:41:55 +0200] "GET /.ab/b1.php HTTP/1.1" 200 149
ip.ip.ip.ip - - [13/Mar/2015:07:41:55 +0200] "GET /.ab/b1.php HTTP/1.1" 200 149
ip.ip.ip.ip - - [13/Mar/2015:07:41:55 +0200] "GET /.ab/b1.php HTTP/1.1" 200 149

Appreciate your help
and thanks in advance!
