Detailed Description

General RequestHandler for the TYPO3 Backend. This is used for all Backend requests except for CLI or AJAX calls. Unlike all other RequestHandlers in the TYPO3 CMS Core, the actual logic for choosing the controller is still done inside places like each single file. This RequestHandler here serves solely to check and set up all requirements needed for a TYPO3 Backend. This class might be changed in the future.

At first, this request handler serves as a replacement to typo3/init.php. It is called but does not exit so any typical script that is not dispatched, is just running through the handleRequest() method and then calls its own code.

However, if a get/post parameter "route" is set, the unified Backend Routing is called and searches for a matching route inside the Router. The corresponding controller / action is called then which returns content.

The following get/post parameters are evaluated here:

• route
• token
