Lighttpd (mostly spoken as Lighty ) is a free web server developed by Jan Kneschke . It implements all the important functions of a web server and, like Apache , can be expanded with modules .


The server relies on asynchronous communication and process multiple requests in a single operating system - process . This enables the web server to process several parallel requests more efficiently and to place less load on the CPU and memory than a multi-process design, for example with the Apache web server . This is particularly useful when large files are being accessed by many users at the same time.

PHP is connected using FastCGI . Perl , Python or Ruby can also be addressed via the SCGI interface. Pages can be generated automatically using the CML (originally: Cache Meta Language) module in Lua , server-side includes are also supported by a module.


According to Netcraft, Lighttpd is spreading quickly and in the "Web Server Survey" of March 2007 made it to 4th place in the ranking with around 1.4 million domains . However, this rating also includes a number of "parked" domains, thousands of which are often on a server, which means that changing large domain dealers can have a major impact on the numbers. In August 2010, the spread was 1.8 million domains.
