Hi , I have 5 sites running in CQ 5.6 and I have 5 apache virtualhost as well , one for each domain , I have 5 farms file for the dispatcher , the problem now is how to setup a replication agent flush per domain? I read this doc http://docs.adobe.com/docs/en/dispatcher/disp-domains.html , but it doesn't work for me ,

I have for example www.site1.com , www.site2.com ... www.site5.com , all runing in cq5.6 , how can invalidate the cache only in site1? whitout change the url invalidation? In the previous link it says to do something like: http://localhost:80/invalidation_only/dispatcher/invalidate.cache. , but who can I invalidate only the site that I need?

The document you referred is right & has additional farm invalidation_only which take care of invalidating for specific site based on stat level & should work. If you are seeing invalidating for other site means you have not followed right structure or configuration.

In case you are trying to have different setup and want to have different flush agents for each site. You can get an idea how to configure from [1] though the example given at [1] was far different use case & will applicable here also.

thanks Sham for your answer , but the farm invalidation_only in that document to invalidate every site under htdocs document root , it creates a stat file in each site , htdocs/content/sitea and htdocs/content/siteb , I need for example only in sitea. That is possible?

Hi Steven,

if configured correctly, the dispatcher invalidates only the part of the content tree, where changes happened.

Hi Jörg , but how could you invalidate only 1 site , lets suppose my example site1 .. until site5 , how can invalidate only site3 for example?

Hi Steven,

Let's assume, you change /content/sitea/home.html and an invalidation is triggered. This invalidation will use the "invalidation_only" farm and therefor invalidate the files in .../htdocs/content/sitea/ (because the docroot of the cache is set to "htdocs" and the full path of the changed page is appended).

The "magic" lies in the fact, that each farm has a different docroot configured:

farm_siteA => htdocs/content/sitea

farm_siteB => htdocs/content/sitea

invalidation_only => htdocs/

it is invalidating only the docroot /var/www instead of /var/www/content/test

apache2.conf

DocumentRoot /var/www/content/test
ServerName test.com

.....

<Directory /var/www/content/test>
   Options Indexes FollowSymLinks
   AllowOverride None
   Order allow,deny
   Allow from all
   RewriteEngine On
<IfModule disp_apache2.c>
   SetHandler dispatcher-handler
ModMimeUsePathInfo On
</IfModule>

</Virtualhost>

DocumentRoot /var/www/

farm_flush.any

...

/virtualhosts
{ "invalidation_only" }

...

/cache
{
# the cacheroot must be equal to the document root of the webserver
/docroot "/var/www"

and in publish instance agent:

http://172.x.x.x:80/invalidation_only/dispatcher/invalidate.cache

Make sure /statfileslevel value of 2 is set

Could you attach complete httpd, virtual & dispatcher any file.
