Differences between F5 and CTRL + F5 in IE

Pressing CTRL + F5 in Internet Explorer is a convenient way to force the page to be reloaded. All components of the page (images, CSS, JavaScript, and so on) are forcibly reloaded. it is equivalent to using an empty cache IE to access a page.

 

F5 is a simple refresh of the current page, click Ctrl + R, or right-click to refresh, it is the same, they have"If-modified"String. If you view F5 trace in NetMon, you will find many HTTP 304 not modified responses under normal conditions.

 

In normal cases, CTRL + F5 is all HTTP 200 OK responses.

 

For another small problem, I will not translate it. In short, before using Ctrl + F5, please click the page you want to refresh.

 

The original text is listed below:

T turns out that Ctrl + F5 only works in IE 7 if the keyboard focus is on the web page itself. if you move the focus anywhere else, such as back to the location bar, it ignores the ctrl key and behaves as if F5 were typed on its own.

So if you really want to do a forced refresh in IE7 make sure you click on the Web page or tab first.
