nocache_headers() WordPress Function
The nocache_headers() function is used to prevent caching of a page or post in WordPress. This function can be useful if you want to make sure that a user always sees the most up-to-date version of a page.
nocache_headers() #
Set the headers to prevent caching for the different browsers.
Description
Different browsers support different nocache headers, so several headers must be sent so that all of them get the point that no caching should occur.
