Cache-Control标头的HTML元标记不适用于chrome

Question

When opening my page I can see the cache-control header is set the right way. I look into the Network tab and check the Response . It says

<meta http-equiv="Cache-Control" content="no-cache"/>

Now looking into the Header tab I can not find this header in the Response Header section. Also other headers set by the meta tag like <meta http-equiv="X-UA-Compatible" content="IE=edge"/> are not listed here:

I read this Is Chrome ignoring Cache-Control: max-age? which mentions that you should open the url in a new tab but I tried that and many other things. Still no look for this headers to be visible.

Any idea what is wrong here?

Answer 1

The header tab show the HTTP headers, not the meta http-equivs in HTML head.

You have to set this HTTP header in your webserver configuration or from within your programming in order to see it in the Response Header section

If you want to check, if your Cache-Control setting is working, don't just reload the page in your browser, but click in the address box and hit enter with the network tab in developer tools open and check the response code.
