Definition: ".Lighttpd" refers to a web server software that allows users to host websites using PHP or other scripting languages. The "conf" part could be interpreted as a file or configuration file associated with Lighttpd, possibly used for security settings or logging purposes. For instance, ".lighttpd.conf" might contain options or rules specific to a particular hosting platform or environment. It's not uncommon for software to use a naming convention like this in the code itself.
