The term responsive generally just indicates that the website uses CSS media selectors in order to modify its layout based upon device attributes. You could probably download any linked CSS and check for the use of media selectors but this is unlikely to be a bullet-proof way of detecting for a responsive site.
Additionally, there's no way you can detect what scripting language is used on the backend of a website. You could guess based upon headers and other information coming back in a response but, again, it's not a bullet-proof way of determining whether the page is dynamically generated or not.
What exactly do you need to do this for?
