======== lighttpd ======== ------------- a light httpd ------------- :author: Jan Kneschke :Date: $Date: 2013/10/14 10:32:47 $ :Revision: $Revision: 1.1.1.1 $ :abstract: lighttpd a secure, fast, compliant and very flexible web-server which has been optimized for high-performance environments. It has a very low memory footprint compared to other webservers and takes care of cpu-load. Its advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and many more) make lighttpd the perfect webserver-software for every server that is suffering load problems. :documentation: http://wiki.lighttpd.net/ the naming ---------- lighttpd is a __httpd__ which is - fast as __light__ning and - __light__ when it comes to memory consumption and system requirements Features -------- Network ``````` - IPv4, IPv6 Protocols ````````` - HTTP/1.0 (http://www.ietf.org/rfc/rfc1945.txt) - HTTP/1.1 (http://www.ietf.org/rfc/rfc2616.txt) - HTTPS (provided by openssl) - CGI/1.1 (http://CGI-Spec.Golux.Com/) - FastCGI (http://www.fastcgi.com/devkit/doc/fcgi-spec.html) Advanced Features ````````````````` - load-balanced FastCGI (one webserver distributes requests to multiple PHP-servers via FastCGI) - custom error pages (for Response-Code 400-599) - virtual hosts - directory listings - streaming CGI and FastCGI - URL-Rewriting - HTTP-Redirection - output-compression with transparent caching FastCGI-Support ``````````````` - parses the Response-header and completes the HTTP-header accordingly - Keep-Alive handling based on Content-Length header PHP-Support ``````````` - same speed as or faster than apache + mod_php4 - handles various PHP bugs in the FastCGI SAPI - includes a utility to spawn FastCGI processes (necessary for PHP 4.3.x) Security features ````````````````` - chroot(), set UID, set GID - protecting docroot HTTP/1.1 features ````````````````` - Ranges (start-end, start-, -end, multiple ranges) - HTTP/1.0 Keep-Alive + HTTP/1.1 persistent Connections - methods: GET, HEAD, POST - Last-Modified + If-Modified handling - sends Content-Length if possible - sends Transfer-Encoding: chunk, if Content-Length is not possible - sends Content-Type - on-the-fly output compression (deflate, gzip) - authentication: basic and digest (http://www.ietf.org/rfc/rfc2617.txt) HTTP/1.1 compliance ``````````````````` - Sends 206 for Range Requests - Sends 304 for If-Modified Requests - Sends 400 for missing Host on HTTP/1.1 requests - Sends 400 for broken Request-Line - Sends 411 for missing Content-Length on POST requests - Sends 416 for "out-of-range" on Range: Header - Sends 501 for request-method != (GET|POST|HEAD) - Sends 505 for protocol != HTTP/1.0 or HTTP/1.1 - Sends Date: on every requests Intended Audience ----------------- - Ad-Server Front-Ends ("Banner-Schleuder") - delivering small files rapidly - php-servers under high load (load-balancing the php-request over multiple PHP-servers) Works with ---------- It has been tested to work with - IE 6.0 - Mozilla 1.x - Konqueror 3.1 (for Keep-Alive/Persistent Connections, Accept-Encoding for PHP + gzip) - wget (for Resuming) - acrobat plugin (for multiple ranges) Works on -------- lighttpd has been verified to compile and work on - Linux - FreeBSD - NetBSD - Solaris 8 + 9 - SGI IRIX 6.5 missing for HTTP/1.1 compliance ------------------------------- - parsing chunked POST request ----------------- Starting lighttpd ----------------- As daemon in the background: :: $ lighttpd -f or without detaching from the console: :: $ lighttpd -D -f
