Bookmarking this, as I intend to build me a home webserver as well. I never heard of lighttpd, good to know it's out there, since I'll probably be using my old P3 laptop for that purpose, so lighter is better.
I built a web server on a virtual machine some time ago, using the httpd, php and mysql packages from slackware. Worked good enough for my testing purposes. You need to open everything up manually, by default everything is closed. Feels safe, not sure if it really is though.
Ps. I can't reach your website right now.
