The Apache Group’s eponymous freeware web server and Microsoft Corp’s Internet Information Server (IIS) continue to pull slowly away from the pack in the race for market share in the web server software market. Apache accounted for 45.7% of the 1,920,933 web sites surveyed, Microsoft 21.8%, Netscape 10.0% and the National Center for Supercomputing Applications server clocked 3.6%. Apache and Microsoft saw their share increase slightly, while the other two dropped slightly, although the actual number of sites using Netscape increased. Around November last year Microsoft overtook Netscape in market share terms and has been moving ahead of the company slowly ever since. Netcraft notes that this month IBM is running http://www.ibm.com for the first time; previously it used a combination of NCSA and other IBM software. It also notes that IBM used Domino-Go-Webserver 4.6 to host the Superbowl.
