Browser Statistics for April 2001


These tables summarize browsers used by 161352 hosts in 122 countries making 2927681 accesses during April 2001 to the Engineering Workstations WWW server at the University of Illinois at Urbana-Champaign. The lion's share of accesses to this server are for engineering student home pages. Information about browser types is extracted from the User-Agent HTTP Request header provided by nearly all browsers.

Hosts, not accesses or people, are summarized in these tables. That is, a host gets only one vote (for its most recently used browser.) Thus browsers on large multi-user Unix systems or proxy servers may in some sense be under-reported, while those on terminal servers or other networks using dynamic addresses may perhaps be over-reported. (Note: during this run 3.7% of the accesses were identifiable as coming from proxy servers.)
