Apache LogFormat: what does %f mean? [closed] January 5, 2024 by Shemaro I have checked the apache logformat from – https://httpd.apache.org/docs/2.4/mod/mod_log_config.html I am not able to understand what does “%f” parameter mean in apache log format. The description given for this parameter is “Filename”. But it does not elaborate which filename. In my case it shows referer url of the http request made.
