A normal HTML page would have an extension of .html or .htm . When a site has an extension like .asp, .shtml, .jhtml, etc., it usually means that certain programming languages are used with the site. I am not sure exactly which ones but I think that's what they mean.
It also depends upon how the server is configured, take for example the W3C http://www.w3.org/ most of their main pages are actually written with PHP but they configure to browser to have *.htm files parsed through PHP *.php so still have *.htm an extension for output.
