lighttpd

Powered by Lighttpd

April 4th, 2007

lighttpd is used by many well-known sites. The typical scenario is using lighttpd as off-load server to push out static content and leave to complex work to another server.

One example is YouTube. They have a farm of servers which push out the thumbnails you see before you see the movies:

$ curl -I http://sjl-static16.sjl.youtube.com/vi/TgF_eRkfqEY/2.jpg
HTTP/1.1 200 OK
Content-Type: image/jpeg
ETag: "983726135810477085"
Accept-Ranges: bytes

Content-Length: 3495
Date: Wed, 04 Apr 2007 06:49:51 GMT
Server: lighttpd-aio/1.4.11.8

As you see in the name-scheme, there are some more of those servers pushing out content.

On wikipedia they run at least 2 servers with lighttpd:

  • upload.wikimedia.org
  • download.wikimedia.org

While download is used to distribute the SQL dumps of the database when tend to grow above the magic 4GByte border, upload is used to push out all the images and resize them when necessary.

$ curl -I http://upload.wikimedia.org/wikipedia/commons/thumb/2/21/Mandel_zoom_00_mandelbrot_set.jpg/250px-Mandel_zoom_00_mandelbrot_set.jpg
