Anticache rules prevent HTTP clients to cache resources that were previously fetched from servers so that clients always try to download the latest version.

To achieve this the rule modify the request headers and response headers that are related to caching:

  • Removes the request headers: If-None-Match and If-Modified-Since
  • Adds the request headers: Pragma: no-cache and Cache-Control: no-cache
  • Removes the response headers: Expires, Last-Modified and ETag
  • Adds the response headers: Expires: 0, Cache-Control: no-cache
