Sometimes we do not want the browser to use caching to speed up the display of the Web page, especially those forums such as frequently updated content of the page, on the internet can be said to use the following methods to screen the cache, but I tried the effect is not good.
<meta http-equiv= "Pragma" content= "No-cache" >
One day I had the whim to find a way to display the most current Web page content in any situation, as described below:
Please change the link of the Web page to:
Http://xxx.yyy.zzz/page.php?rand=XXXXXXX
Where http://xxx.yyy.zzz/page.php is your Web page, Rand is a Qurey string that you don't use, and xxxxxxx is a random string.
That is, if you add a random string that does not affect the content of the Web page at the URL of the link, so that the URL for each visit to the page is different, so that the browser does not use the page already in the cache, so that each display is the latest content.
