What is caching in TYPO3?
=========================

Caching is a process TYPO3 uses to temporarily store content and data to help
your website load faster and perform efficiently. Instead of regenerating
every page or content piece each time a visitor loads it, TYPO3 saves a
"cached" version. This way, the system can quickly serve this saved content,
reducing the load on the server and speeding up the response time for users.

How to clear caches in TYPO3?
=============================

When you update content or make configuration changes, TYPO3 sometimes needs a
cache refresh to reflect these updates on the live site.
Here are the main ways to clear caches in TYPO3 13:

*   Clearing Cache in the backend:

    *   In the Backend, look for the Clear cache icon, which resembles a
        lightning bolt. You can find this in the `top bar <https://docs.typo3.org/permalink/t3start:top-bar>`_.

    *   For deeper cache management, you can use the Install Tool:
        In :guilabel:`Admin Tools > Maintenance` you can find the option to
        clear all caches. This will refresh everything, including caches
        that aren't typically cleared through the backend top bar.

*   Clearing caches via Command Line

    For advanced users or developers, caches can also be cleared from
    the command line:

    ..  code-block:: bash

        ddev typo3 cache:flush

.. _when-to-clear-cache:

When should you clear caches?
=============================

*   If new content, images or text doesn't show up right away.
*   When adjusting templates, extensions or system settings.
*   While working on custom code, plugins or during site updates.
