Set up Sling Dynamic Include

1. Download and install the [Sling Dynamic Include] bundle .
2. Configure Sling Dynamic Include via the OSGi Configuration Factory at http://<host>:<port>/system/console/configMgr/org.apache.sling.dynamicinclude.Configuration .
   Or, to add to an AEM code-base, create the appropriate sling:OsgiConfig node at:

   <?xml version="1.0" encoding="UTF-8"?>
   <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0"
       xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
       jcr:primaryType="sling:OsgiConfig"
       include-filter.config.enabled="{Boolean}true"
       include-filter.config.path="/content"
       include-filter.config.resource-types="[my-app/components/content/highly-dynamic]"
       include-filter.config.include-type="SSI" 
       include-filter.config.add_comment="{Boolean}false"
       include-filter.config.selector="nocache"
       include-filter.config.ttl=""
       include-filter.config.required_header="Server-Agent=Communique-Dispatcher"
       include-filter.config.ignoreUrlParams="[]"
       include-filter.config.rewrite="{Boolean}true"
       />
   <!--
   * include-filter.config.include-type="SSI | ESI | JSI"
   * include-filter.config.ttl is # of seconds (requires AEM Dispatcher 4.1.11+)
   -->
   
   

3. (Optional) Repeat the last step to allow for components on locked (initial) content of editable templates to be served via SDI as well. The reason for the additional configuration is that locked content of editable templates is served from /conf instead of /content .

   <?xml version="1.0" encoding="UTF-8"?>
   <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0"
       xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
       jcr:primaryType="sling:OsgiConfig"
       include-filter.config.enabled="{Boolean}true"
       include-filter.config.path="/conf"
       include-filter.config.resource-types="[my-app/components/content/highly-dynamic]"
       include-filter.config.include-type="SSI" 
       include-filter.config.add_comment="{Boolean}false"
       include-filter.config.selector="nocache"
       include-filter.config.ttl=""
       include-filter.config.required_header="Server-Agent=Communique-Dispatcher"
       include-filter.config.ignoreUrlParams="[]"
       include-filter.config.rewrite="{Boolean}true"
       />
   <!--
   * include-filter.config.include-type="SSI | ESI | JSI"
   * include-filter.config.ttl is # of seconds (requires AEM Dispatcher 4.1.11+)
   -->
   
   

4. Update Apache HTTPD Web server's httpd.conf file to enable the Include module.

   $ sudo vi .../httpd.conf
   
   

   LoadModule include_module libexec/apache2/mod_include.so
   
   

5. Update the vhost file to respect include directives.

   $ sudo vi .../vhosts/aem-publish.local.conf
   
   

   <VirtualHost *:80>
   ...
      <Directory /Library/WebServer/docroot/publish>
         ...
         # Add Includes to enable SSI Includes used by Sling Dynamic Include
         Options FollowSymLinks Includes
   
         # Required to have dispatcher-handler process includes
         ModMimeUsePathInfo On
   
         # Set includes to process .html files
         AddOutputFilter INCLUDES .html
         ...
      </Directory>
   ...
   </VirtualHost>
   
   

6. Update the dispatcher.any configuration file to support (1) nocache selectors and (2) enable TTL support.

   $ sudo vi .../conf/dispatcher.any
   
   

   /rules {
     ...
     /0009 {
       /glob "*.nocache.html*"
       /type "deny"
     } 
   }
   
   

   Leaving the trailing * off in the glob *.nocache.html* rule above, can result in issues in requests for sub-resources .

   /cache {
       ...
       /enableTTL "1"
   }
   
   

7. Always restart Apache HTTP Web Server after making changes to its configuration files or the dispatcher.any .

   $ sudo apachectl restart
