Problem/Motivation

When a Drupal message is set, Drupal creates an anonymous session to show the message on the page, the result is a different page uncached. Because large sites could have a lot of access denied due to unpublished nodes or not accessible content, this must be avoided.

Steps to reproduce

  • Try to access as an anonymous user to unpublished content with the Develop web-browser tools opened
  • Review the headers of the redirection and the cacheability of the page

Anonymous cookie session on the Network tab:

Proposed resolution

To avoid generating a different page when showing a message, a solution could be to use a flag in the URL, if the flag is present, then show the Drupal message using javascript.
Example:
/user/login?destination=hola-mundo#access-denied
