Collect HTML for pages by calling page controllers directly

[7h3Rabbit]

Currently we are collecting HTML for pages by requesting the content over HTTP(s).
It would be nice if we could remove the need of using HTTP(s), because:

• Not required to supply URL with anonymous access (that could be a different server and could have old content)
• Minimizing the risk to get old/cached content

This could be done by calling the page controllers directly
