NASA JPL (Jet Propulsion Laboratory at the California Institute of Technology in Pasadena) is one of the most popular Web destinations right now. The next time you visit http://www.jpl.nasa.gov/ pay close attention to the URLs, lots of them have a .cfm extension. JPL has been using ColdFusion for a long time, ever since CGI and DBML days. This site appears to be running ColdFusion 5 on Linux. It is not an MX site (yet), but still, it is another great example of ColdFusion powering high profile high volume sites. Thanks to Alex Hubner for pointing this one out to me.
