通过浏览器缓存java脚本

Question

I'm wandering how does browser caches the javascript files. I have utility.js and I use it on multiple pages. I know that when I go to www.some_host/page1.html the utility.js is cached for that request. What happens if I go to different page www.some_host/page2.html, utility.js is requested again from server or take it from browser cache?

Answer 1

Everything is cached based on its own URI. It doesn't matter what caused the browser to load it (unless you have something like Vary: referer in the headers, which I've never seen)

Answer 2

浏览器通常遵循用于其他资源（页面，图像等）的缓存规则。
