如果使用F5刷新我的网络应用程序是非常缓慢和挂起，而点击输入地址栏立即刷新页面？

Question

I have a web page which uses in PHP and a jQuery DataTable to show data from a database.

When I enter the URL and hit enter, the page loads instantly, and I can do this repeatedly and the page keeps loading instantly.

However, when I hit F5, the page goes blank and hangs, it is trying to load the page but is just too slow.

What would be causing this?

Answer 1

Have you actually confirmed your page is really being reloaded?

Most of the time, hitting enter in the address bar if you're already on the page, will merely cause the browser to load it from its cache. Pressing F5 or reload on the other hand would cause the actual round-trip to the server.
