Etag Verification

The Etag Verification feature in the Medianova Cloud Panel for dynamic content allows the CDN to validate cached dynamic content against the origin server using entity tags (ETags). This ensures that the dynamically generated resources are up-to-date and that the CDN only refreshes the cache when the content has changed, optimizing both performance and accuracy.

Key Features

• Etag Validation:

  • When enabled, the Etag header is used to check the validity of cached dynamic content. This ensures that the content served from the CDN is always synchronized with the most recent version from the origin server. The Etag helps prevent the delivery of outdated or incorrect content, especially for dynamic resources that might change frequently based on user interactions, session data, or real-time information.

By using Etag Verification for dynamic content, you ensure that the CDN serves the freshest version of dynamic resources without unnecessarily re-fetching them from the origin server, improving load times and resource utilization. This is especially beneficial for dynamic content that changes often, such as personalized data, real-time updates, or API responses.
