What are common file extensions for web programming languages?

What file extensions are used most commonly by different languages? Please don't put source file names (like .java) but rather extensions that would be present in a URL for rendered pages. Here is my (alphabetized) list so far - ASP Classic - asp - ASP.NET - aspx - axd - asx - asmx - ashx - CSS - css - Coldfusion - cfm - Erlang - yaws - Flash - swf - HTML - html - htm - xhtml - jhtml - Java - jsp - jspx - wss - do - action - JavaScript - js - Perl - pl - PHP - php - php4 - php3 - phtml - Python - py - Ruby - rb - rhtml - SSI - shtml - TS - XML - xml - rss - svg - Other (C, perl etc.) - cgi - dll Any more? I'll keep updating this based on comments. Largest correct additions (or deletions) is the accepted answer.
