Fortune 1000 app servers: 43.6% use ASP.NET, 12.2% use J2EE, 5.2% use PHP

In May 2005, Port80 Software launched the survey of application servers and scripting platforms used on the main corporate Web sites of the Fortune 1000 (based on the 2005 Fortune 1000 list of companies).

In May 2005, Port80 Software launched the survey of application servers and scripting platforms used on the main corporate Web sites of the Fortune 1000 (based on the 2005 Fortune 1000 list of companies). This survey analyzes HTTP header signatures to determine the presence of an application server or scripting technology, and since some servers are configured with more than one backend (for instance, classic ASP and ASP.NET) and/or have no application server present, the percentages above do not add up to 100%. However, this survey does discount for duplication within categories.
