Origins of "pretty url"?

This seems to be an official way to refer to it, as it's even got a redirect on Wikipedia and some of Google's ajax crawling documentation calls it a pretty url as开发者_如何学运维 well. Heck, SO has 44 questions tagged pretty-url even. I do get that it is nicer looking to have /post/1/ than /post.php?id=1, but who first called it a "pretty url"? When was the term popularized, and by who?

I guess this appelation became popular because of php and java cms which name there rewriting modules "Pretty Url". Now it's nearly impossible to say which is the original author of this sentence !
