Lighttpd

mod_indexfiles (with an s at the end) is used twice instead of mod_indexfile, which might lead to errors or confusion:

lighttpd-1.4.22/configure.in:560:do_build="mod_cgi mod_fastcgi mod_extforward mod_proxy mod_evhost mod_simple_vhost mod_access mod_alias mod_setenv mod_usertrack mod_auth mod_status mod_accesslog mod_rrdtool mod_secdownload mod_expire mod_compress mod_dirlisting mod_indexfiles mod_userdir mod_webdav mod_staticfile mod_scgi mod_flv_streaming" 

lighttpd-1.4.22/src/configfile-glue.c:52:                             * this is used to prepend server.modules by mod_indexfiles as it has to be loaded
