How dispatcher fulfill request?

When clients send HTTP requests to the web server, the URL of the requested page must be resolved to the content in the Dispatcher cache, and eventually to the content in the repository.

 

1. The domain name system discovers the IP address of the web server which is registered for the domain name in the HTTP request.
2. The HTTP request is sent to the web server.
3. The HTTP request is passed to Dispatcher.
4. Dispatcher determines whether the cached files are valid. If valid, the cached files are served to the client.
5. If cached files are not valid, Dispatcher requests newly-rendered pages from the AEM publish instance.
