I saw some web sites using .epc or .wws for some programming pages.
What is .epc?
And what is .wws?
Are these technologies too old or too new. I never heard of it.
Or they just called it .epc or wws, but in their site set up, they may parse .epc or .wws files as .php? I doubt that, why bother use these strange extensions if it is just a php or cgi pages?
Thanks!
What some sites do is use a completely random file extension then (as you said) parse it as whatever programming language they are using.
A good example is flickr. they use a .gne extension.
You can look up any extension here, for future reference.
Yup, the thing to keep in mind is that the extension need have nothing to do with what is going on in the background. If anything, it should reflect the content of the response (so most ".php" pages should have an ".html" extension). But even that is delving too far into the rude mechanicals than the W3C suggests is wise.
What to leave out.
Everything!

File name extension. This is a very common one. "cgi", even ".html" is something which will change. You may not be using HTML for that page in 20 years time, but you might want today's links to it to still be valid. The canonical way of making links to the W3C site doesn't use the extension.
