浏览器是否缓存PHP生成的CSS和Javascript文件?

Simple question.

Do browsers cache PHP generated CSS and script files automatically, just like CSS/JS files?

    If the URL remains the same, and there aren't hints in the HTTP responses to tell the browser otherwise, they can be cached.

    If the URL includes dynamic information, the browser probably won't be able to take advantage of caching.

    Changing the URL by adding a timestamp as a dummy parameter (e.g. http://host/myfile.php?t=17279273) is one of the ways you can prevent caching since the browser sees the slight change as a new resource.
