Fortunately, developers can leverage meta HTML tags to control caching behaviour, ensuring users receive the latest content promptly. The http-equiv attribute of the element allows you to provide processing instructions for the browser as if the response that returned the document included certain HTTP headers.The metadata is document-level metadata that applies to the whole page. This is similar to the cache control meta tag having a no-cache attribute which makes the browser not cache the page.

http-equiv attribute
See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. Through the use of the expiration ate in the past, the browser should regard the file as expired and not cache it. There instead, the output though is seen in the actions of the browser’s caching mechanism when you visit the page. Browser caching, while speeding up website loading, poses challenges in serving recent updates.
Using the Cache-Control Meta Tag
Sets a default language for the document used by assistive technologies or styling by the browser.Similar to the Content-Language HTTP header.Use the lang attribute instead. We have entered the meta http equiv to disable browser caching ? HTML lets you specify metadata – additional important information about a document in a variety of ways. See the The WCAG 2.0 Documents for an explanation of how this document fits in with other Web Content Accessibility Guidelines (WCAG) 2.0 documents. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
