SSL Problem: Client Side Caching (JS/CSS)
问题 It appears that SSL causes a browser (at least FF 3.0.14) to re-request unchanged JavaScript and CSS every time, and doesn't cache either resource at all. That's a significant bandwidth increase in my case (about 80 KB instead of ~3 KB per request). How can I enforce/promote caching of my JS/CSS files the regular way on the client browser? 回答1: Try serving the Javascript from a non-SSL domain, see if that does the trick. 来源： https://stackoverflow.com/questions/1448065/ssl-problem-client-side
