Clear browser cache and mail browser cache

For mobile web development, you can scan pages for debugging. android browsers always cache html static resources by default, every time static resources change or even when new content is released, it is very likely that it cannot be updated in the browser. It is annoying to clear the cache to see the effect. Some customers have installed QQ browsers, which actually call the QQ browser. Sometimes even the cache is invalid, and the QQ browser cache needs to be cleared.

The solution is to add the following header information to the debugging or frequently updated page.

<Meta http-equiv = "Cache-Control" content = "no-cache, no-store, must-revalidate "/> <meta http-equiv =" Pragma "content =" no-cache "/> <meta http-equiv =" Expires "content =" 0 "/>
