此外，還可以查看資源是否從瀏覽器緩存中加載。
There are lots of issues and solutions around this, but in this case you have at least one thing going for you—the browser cache.
雖然存在許多有關(guān)這方面的問題和解決方案，但是在這種情況下您至少有一件事情要去做 — 瀏覽器緩存。
If a valid response can be found in the browser cache, the browser displays the content to the end user without sending a request to the network.
如果可以在瀏覽器緩存中找到有效的響應(yīng)，瀏覽器將不向網(wǎng)絡(luò)發(fā)送請求，而直接將此內(nèi)容向最終用戶顯示。

One on the server, the other in your browser (or cache, whatever).
