AEM as a Cloud local dispatcher does not have statfile

I have Dispatcher running locally, and there does not appear to be any statfile in the cache.

I have the statfilelevel "2"

I have published a page, fetched it through the dispacther, then updated the content on Author and published again.

The Dispatcher Flush agent is running on the Author and the logs show successful replication and invalidate.

Looking at the Dispatcher logs I see the message "never flushed".

 

the http://localhost:8080/dispatcher/invalidate.cache ruturns "It Worked", but the files remain.

 

Am I missing something here?

It appears the dispatcher which comes from the AEM Cloud SDK contains many immutable files, even though you give a path to your local dispatcher source.  So even though you change values locally, they are never taken into consideration.

For instance: default_invalidate.any cannot be changed to allow 127.0.0.1 to invalidate the cache, therefore on page activation the cache is never flushed.

My solution was to setup the Dispatcher on my Mac and change the dispatcher configurations, which produced the .stat files corrected.

Also, to run /dispatcher/invalidate.cache I discovered that it should be performed using Postman since the Headers CQ-Action, CQ-Handle and Content-Length need to be passed to the call.

i believe with invalidate its just invalidate the files and won't delete it physically from the cache directory. the file will be get freshly cached once that files is requested again after the invalidate

    Thanks for your reply, but the missing statfile still makes me scratch my head.  

    I have run dispatcher/invalidate.cache and then requested a file which serves the old file still in cache.

      If you haven’t configured statfile property on dispatcher then by default it creates a .stat file and it’s creation depended on statfilelevel as well. So check on your windows if you can see the “.stat” file there

        Here is from the log

        00 /cache {
        2023-05-01 08:46:00 /docroot "/mnt/var/www/html"
        2023-05-01 08:46:00 /statfileslevel "2"
        2023-05-01 08:46:00 /allowAuthorized "0"
        2023-05-01 08:46:00 /serveStaleOnError "1"
        2023-05-01 08:46:00 /rules {
        2023-05-01 08:46:00 /0000 {
        2023-05-01 08:46:00 /glob "*"
        2023-05-01 08:46:00 /type "allow"

        ....

         

        There is no stat file in html directory or content directory or subdirectory

         

        /mnt/var/www/html # ls -lta
        total 0

            level 4

            I think it is something with the AEMaaC dispatcher configuration and I can't change 

            default_invalidate.any which contains ${AEM_IP} for the dispatcher invalidate

              To test if .stat file is created or not can you increase the statfilelevel to 6 and publish the page at level 4
