Open Source Parking Spoofing Headers to Benefit Apache

HTTP header order is often characteristic of a web server. The opensourceparking.com headers say Apache, but have the Date & Server headers last, a pattern which is identical to the lighttpd response and entirely unlike a typical Apache response. The etag is also not in Apache format, and matches the lighttpd format:

Perens downplayed the significance of Microsoft’s market share gains because they relied upon parked domains. “This is an ‘appearance’ change only, because the sites involved have no content,” he wrote in announcing the service. “But managers believe figures like those in the Netcraft report, and act on them.”

Apache is used by domain registrars Register.com, 1&1 Internet, Dotster and DirectNIC, while Demand Media/eNom uses Windows Server 2003.
