What are common file extensions for web programming languages?

Question

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
• 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.

Solution 1

Add there:

• ASP.NET
  • .axd
  • .asx
  • .asmx
  • .ashx
  • .aspx

Solution 2

Keep in mind that good URL design will completely hide any underlying file types.

Solution 3

I have created a Github gist that contains a list of programming languages and their extensions, here is a subset of the data included in the gist file:

{
  "name":"CoffeeScript",
  "type":"programming",
  "extensions":[
     ".coffee",
     "._coffee",
     ".cake",
     ".cjsx",
     ".cson",
     ".iced"
   ]
  },{
  "name":"ColdFusion",
  "type":"programming",
  "extensions":[
     ".cfm",
     ".cfml"
  ]}

I hope it is helpful.

languages.json.

Solution 4

• .action — struts2

• .do — struts1

• .xml — XML

• .rss — RSS feeds

• .atom — Atom feeds(RSS)

(no extension) -- used now a days to increase readability of the URL, check stackoverflow URL

Here is an extension you forgot:

• .adp — AOLServer using TCL
