+================================================
+Deprecation: #83853 - Backend AjaxRequestHandler
+================================================
+
+See :issue:`83853`
+
+Description
+===========
+
+The class :php:`\TYPO3\CMS\Backend\Http\AjaxRequestHandler` has been marked as deprecated and will be removed in TYPO3 v10.
+This functionality has been moved into the backend's generic Request Handler functionality.
+
+The AJAX functionality itself is not deprecated and can be used as before.
+
+
+Impact
+======
+
+Installations that use :php:`\TYPO3\CMS\Backend\Http\AjaxRequestHandler` will trigger a deprecation warning.
+
+
+Affected Installations
+======================
+
+All installations that use custom extensions that add classes derived from :php:`\TYPO3\CMS\Backend\Http\AjaxRequestHandler`.
+
+
+Migration
+=========
+
+Use a PSR-15 middleware for the Backend Middleware Stack or extend from the generic
+:php:`\TYPO3\CMS\Backend\Http\RequestHandler` instead.
