Unable to flush dispatcher cache on publish

Hi @nitrohazedev ,

• Publication and cache invalidation take place at the same time. Depending on the timing a user may request a page just after it was removed from the cache and just before the new page is published. AEM now returns the old page and the Dispatcher caches it again. This is more of an issue for large sites.
• Hitting by queryString param will not clear cache but serves the content from publisher.

For more details to check what is missing please check these article having 4 steps to get it done: https://sourcedcode.com/blog/aem/how-to-setup-the-aem-dispatcher-flush-agent

Additionally, you can invalidate the dispatcher cache manually: https://experienceleague.adobe.com/docs/experience-manager-dispatcher/using/configuring/page-invalidate.html?lang=en#:~:text=To%20invalidate%20(or%20flush)%20the,specific%20files%20from%20the%20cache.

Question about about your /statfileslevel It depends on your project structure please check Invalidating Files by Folder Level how it works: https://experienceleague.adobe.com/docs/experience-manager-dispatcher/using/configuring/dispatcher-configuration.html?lang=en#invalidating-files-by-folder-level 

• When a file located at a certain level is invalidated then all .stat files from the docroot to the level of the invalidated file or the configured statsfilevel (whichever is smaller) will be touched.

  • For example: if you set the statfileslevel property to 6 and a file is invalidated at level 5 then every .stat file from docroot to 5 will be touched. Continuing with this example, if a file is invalidated at level 7 then every . stat file from docroot to 6 will be touched (since /statfileslevel = "6").

Only resources along the path to the invalidated file are affected. Consider the following example: a website uses the structure /content/myWebsite/xx/. If you set statfileslevel as 3, a .statfile is created as follows:

• docroot
• /content
• /content/myWebsite
• /content/myWebsite/*xx*

When a file in /content/myWebsite/xx is invalidated then every .stat file from docroot down to /content/myWebsite/xxis touched. This would be the case only for /content/myWebsite/xx and not for example /content/myWebsite/yy or /content/anotherWebSite. 

Hope that helps!

Santosh
