Lightweight Web Serving with thttpd
Julio M. Merino Vidal
introduces thttpd on O'Reilly.
"
The Apache HTTP Server is the most popular web server due to its functionality, stability, and maturity. However, this does not make it suitable for all uses: slow machines and embedded systems may have serious problems running it because of its size. Here is where lightweight HTTP servers come into play, as their low-memory footprints deliver decent results without having to swap data back to disk."
