PLEASE NOTE: Native Lighttpd Windows builds are available at http://en.wlmp-project.net/
The last available Lighttpd for Windows build that I created using Cygwin was Lighttpd for Windows 1.4.17. Updated September 29, 2009.
Lighttpd 1.4.15 for Windows is now available for download in the normal place.
If upgrading, backup your current install first to be on the safe side.
The new mod_extforward has been removed, since it won’t compile in Cygwin.
For a list of all the changes, please read the included README.txt which is shown within the installer, especially the changelog section.
