• Running Microsoft-IIS 6.0 and ASP.NET 2.0.50727. The Bush administration ran Apache on what I think was some sort of Unix. Data is gzip’d.
• Whitehouse.gov is using Akamai as a CDN and for DNS service.
• Using jQuery 1.2.6 (someone should let them know 1.3 is out). Also using several plugins including jQuery UI, jcarousel, Thickbox. Also using swfobject.
• Pages tentatively validate as XHTML 1.0 Transitional! I’m shocked by this. I’ve checked several pages all with the same result.
• Using WebTrends for analytics. Bush Administration also did.
• IE Conditional Stylesheets and a print stylesheet.
• RSS feeds are actually Atom feeds.
• The website is setting two cookies that I can see WT_FPC and ASP.NET_SessionId which expire at the end of the session which is not prohibited in federal government as per OMB Guidance for Implementing the Privacy Provisions of the E-Government Act of 2002 (using Google Cache for that link since I can’t find it anywhere else, our government should really keep those in a more permanent location).

I should note that this is quite different in architecture than the Obama campaign site which ran PWS/PHP, no notable JS library, feed, and Google Analytics.
