SAN DIEGO, Calif., - November 23, 2004 — Port80 Software released new surveys of the Web server technology used by U.S. Fortune 1000 companies on their main corporate Web sites. November 2004 shows continued gains for Microsoft's Windows® Server 2003/IIS 6.0 and an increasing adoption of performance best practices like HTTP compression and expiration-based cache control among Fortune 1000 Web sites.
"Instead of a popularity contest, Port80 Software focuses on the technologies and practices employed by the largest corporate Web sites," said Joseph Lima, COO of Port80 Software. "Also, we look for technologies that Port80 develops and are excited to see cache control and compression as emerging Fortune 1000 Web standards."
Port80 Software's Top 1000 Corporations Web Servers Survey examines Web server market share and offers a counterpoint to the Netcraft Web Server Survey. While Netcraft examines Internet domains as a whole, Port80's survey focuses on major U.S. corporations with large investments in their Web presence.
Among the Fortune 1000, Microsoft Internet Information Services (IIS) is the clear leader with a 53.8% market share, Apache is second with 21.2%, and Netscape trails with 13.2%. While 2004 has seen minor fluctuations in overall market share, there have been significant changes within the Microsoft IIS numbers. IIS 6.0 on Windows Server 2003 has grown by 7.5% in the past 12 months, signaling confidence in Microsoft's latest server OS and upgrades from Windows NT.
Port80's Web Technology Surveys also explore the Fortune 1000's use of HTTP compression and cache control for Web acceleration, bandwidth savings, and server consolidation.
November marks the debut of Port80's Top 1000 Cache Control Survey, studying the Fortune 1000's use of expiration-based cache control headers. In the first survey of its kind, Port80 found that 21.1% of Fortune 1000 home pages use explicit caching policies, easing server strain and speeding up page load times by reducing cacheable requests by 28.1% for repeat visitors.
Port80's Top 1000 HTTP Compression Survey shows a slow but steady adoption of HTTP compression, and the November survey found that 7 more Fortune 1000 Web sites have implemented compression since June 2004, bringing the total up to 6%. HTTP compression saved those 60 sites an estimated 23.5% in bandwidth expenses on their home pages alone while providing acceleration for site visitors.
