5. Prevent others from calling your page in the frame

6. Automatic jump (this tag usage allows a web page to automatically jump from the current page to another page or website after how many seconds)

Content is followed by a value of how long the current page jumps.

The parameter to content is all,none,index,noindex,follow,nofollow. The default is all. If you do not add this tag to a page, by default content= "all" means to search and include crawling this page and this page pointing to the page.
