Today, when I searched for a page on Baidu, because the page has been deleted, I naturally used Baidu snapshots to open Baidu snapshots, but it showed: Sorry, the web page you are viewing does not allow Baidu to save its snapshots, so I thought of writing down how to set the method to prohibit Baidu snapshot cache, the method is as follows:
Add between <head> and </head> web pages that need to be banned from Baidu cache
<meta name=Baiduspider content=noarchive>
Similarly, if all search engine caches need to be prohibited, it is to add the pages <head> to </head> that need to be prohibited.
<meta name=ROBOTS content=noarchive>
