The unknown format, 3
The popular web server Apache does not deliver .svg or .svgz files with the correct headers, with the consequence that no browser will be able to render .svg line art directly. Fortunately, there is an easy fix.
To my dismay, dhttpd suffers from the same limitation. Thanks to Haui, who created a patch, and piet, who applied it, this dhttpd delivers .svg line art correctly -- allowing me to display facts and figures in an aesthetically pleasing way while retaining a snappy response even for low-bandwidth connections. 😊
