A scheme where web server serves a default file on per-subdirectory basis has been supported as early as NCSA HTTPd 0.3beta (22 April 1993),[2] which defaults to serve index.html file in the directory.[2][3] This scheme has been then adopted by CERN HTTPd since at least 2.17beta (5 April 1994), which its default supports Welcome.html and welcome.html in addition to the NCSA-originated index.html.[4]
