Dispatcher | Cache invalidation not working locally

Level 3

Dear AEM community,

I faced a problem when i configured a dispatcher cache flush.

After enabling the flush agent, clicking test logs this:

Replication test to http://localhost:8080/dispatcher/invalidate.cache

18.02.2015 12:00:11 - Create new HttpClient for Dispatcher Flush
18.02.2015 12:00:11 - * HTTP Version: 1.1

Any ideas what is probably not configured properly?

Also when i configured the dispatcher module, i changed the file "dispatcher.any" to "myhost.any". 

Maybe the issue above is affected to the path /dispatcher/invalidate.cache or i missed out to configure anything.

 

Thanks,

Thuong.

Message from support on this: 

The dispatcher might not be active on the path /dispatcher/invalidate.cache if DispatcherDeclineRoot 1 and the dispatcher-handler is only enabled for a particular URL location.

Basically the flush request must be received at a path where dispatcher will handle the request.  I would request they review the dispatcher.log with debug logging enabled.  If the request is not showing in the dispatcher.log then it is some configuration in the web server and they would need to provide their dispatcher configs and web server configs.

Dear smacdonald2008edubey,

 

Thanks for your support. I resolved by re-configuration httpd.conf

Hi TinyT,

We are also facing the same issue in our application. But the issue is not frequent. Replication works fine for 5 days and it stops after 5th or 6th day. We observed that the replication is blocked at the dispatcher level and we also got the same issue. 

Can you please let us know how you have fixed the issue. What configuration changes you have done in httpd.conf?

 

Thanks,

Swapna

Hi Swapna,

We need to  double check on the dispatcher.any and we should update

  • /allowedClients

and added the ip of publish server.

also you can check the docroot configuration.

 

Thanks,

Thanks Thuong. But this dispatcher flush works fine for few days and it stops suddenly after 5th or 6th day. Did you faced this issue any time.

 

Thanks,
