Configuration File Options¶

Here you will find a list of all available configuration lighttpd. They are grouped by module, and a link to each module configuration will provide with more detail information about each option, as well as examples, and other guidelines.

Modules must be listed in server.modules or else options from that module will be recognized by lighttpd. e.g. server.modules += ("mod_example") (The only exceptions are the three core modules that lighttpd loads by default: mod_indexfile, mod_dirlisting, mod_staticfile)
