The <meta> tag defines metadata about an HTML document. Metadata is data (information) about data. <meta> tags always go inside the <head> element, and are typically used to specify character set, page description, keywords, author of the document, and viewport settings.

Beyond the validation error, this approach has always been unreliable. Browsers and caching proxies generally ignore http-equivmeta tags for cache control purposes — they rely on actual HTTP response headers sent by the server. Keeping this invalid tag in your HTML provides a false sense of security while producing no real caching benefit.
