What is the possible advantages/disadvantages of page caching? How can you prevent caching of a certain page?

When we use the metatag in the header section at the beginning of an HTML Web page,
the Web page may still be cached in the Temporary Internet Files folder.
A page that Internet Explorer is browsing is not cached until half of the 64 KB buffer is filled. Usually, metatags are inserted in the header section of an HTML document, which appears at the beginning of the document. When the HTML code is parsed, it is read from top to bottom. When the metatag is read, Internet Explorer looks for the existence of the page in cache at that exact moment. If it is there, it is removed.

To properly prevent the Web page from appearing in the cache, place another header section at the end of the HTML document
