Each Application class registers Request Handlers to the TYPO3 Bootstrap to run a certain request type (e.g. eID or TSFE-logic, or AJAX requests in the Backend). Each Application is handed over the Class Loader provided by Composer. There are four types of Applications provided by the TYPO3 Core: \\TYPO3\\CMS\\Frontend\\Http\\Application ----------------------------------------- All incoming web requests coming to index.php in the main directory, handling all TSFE and eID requests. The Application sets TYPO3_MODE=FE very early. The Application checks if all configuration is given, otherwise redirects to the TYPO3 Install Tool. \\TYPO3\\CMS\\Backend\\Http\\Application ---------------------------------------- All incoming web requests for any regular Backend call inside typo3/\*. This handles three types of Request Handlers: - The AJAX Request Handler, which is triggered on requests with an "ajaxID" GET Parameter given. - The Backend Module Request Handler, which handles all types of modules triggered on requests with an "M" GET Parameter - The regular Request handler for typical other backend calls on index.php. The Application checks if all configuration is given, otherwise redirects to the TYPO3 Install Tool. \\TYPO3\\CMS\\Backend\\Console\\Application ------------------------------------------- All CLI Requests handled by cli_dispatch.php. Only executes the parts that are necessary for Backend CLI Scripts used with the cliKey syntax. The typical CliRequestHandler is used for handling requests set up by this Application. \\TYPO3\\CMS\\Install\\Http\\Application ---------------------------------------- The install tool Application only runs with a very limited bootstrap set up with a Failsafe Package Manager not taking the ext_localconf.php scripts of installed extensions into account. .. index:: PHP-API
