'''thttpd''' (tiny/turbo/throttling HTTP server) is an [[open source software]] [[web server]] from ACME Laboratories, designed for simplicity, a small [[Memory footprint|execution footprint]] and speed. 

== Design and features == 
thttpd is [[Thread (computer science)|single-threaded]] and [[Software portability|portable]]: it compiles cleanly on most [[Unix-like]] [[operating system]]s, including [[FreeBSD]], [[SunOS]] 4, [[Solaris (operating system)|Solaris]] 2, [[BSD/OS]], [[Linux]], and [[OSF/1]]. It has an executable memory size of about 50 kB.<ref>{{cite web|url=http://www.acme.com/software/thttpd/benchmarks.html|title=Web Server Comparisons|publisher=acme.com}}</ref>
While it can be used as a simplified replacement to more [[feature-rich]] servers, it is uniquely suited to service high volume requests for static data&mdash;for example as an [[Image hosting service|image hosting server]]. The first "t" in thttpd stands for variously tiny, turbo, or throttling.

thttpd has a [[bandwidth throttling]] feature which enables the server administrator to limit the maximum [[bit rate]] at which certain types of files may be transferred.  For example, the administrator may choose to restrict the transfer of [[JPEG]] image files to at most 20 [[kilobyte]]s per second.  This prevents the connection from becoming saturated so that the server will still be responsive under heavy load, with the tradeoff that file transfer speed is reduced. thttpd does not support the [[X-Forwarded-For]] header.<ref>{{cite web|url=http://wiki.nginx.org/ThttpdRealIP|title=thttpd patch|website=wiki.nginx.org}}</ref><ref>[http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=119888 Debian bug of thttpd does not respect X-Forward-For header] (closed)</ref>

== Forks ==
There are at least 2 public [[Fork (software development)|fork]]s of thttpd:
* [https://github.com/blueness/sthttpd sthttpd] by Anthony Basile, focusing on [[Gentoo Linux]] patches
* [https://github.com/troglobit/merecat/ Merecat] by Joachim Nilsson, adding a number of features, most notably [[Secure Sockets Layer|SSL]] support
