+
+   Don't activate the favicons before reading the documentation.
+

+   :depth: 2
+   :local:
+   :backlinks: entry
+
+Activating the favicons in SearXNG is very easy, but this **generates a
+significantly higher load** in the client/server communication and increases
+resources needed on the server.
+
+To mitigate these disadvantages, various methods have been implemented,
+including a *cache*.  The cache must be parameterized according to your own
+requirements and maintained regularly.
+
+To activate favicons in SearXNG's result list, set a default
+``favicon_resolver`` in the :ref:`search <settings search>` settings:
+
+.. code:: yaml
+
+   search:
+     favicon_resolver: "duckduckgo"
+
+By default and without any extensions, SearXNG serves these resolvers:
+
+- ``duckduckgo``
+- ``allesedv``
+- ``google``
+- ``yandex``
+
+With the above setting favicons are displayed, the user has the option to
+deactivate this feature in his settings.  If the user is to have the option of
+selecting from several *resolvers*, a further setting is required / but this
+setting will be discussed :ref:`later <register resolvers>` in this article,
+first we have to setup the favicons cache.
+
+Infrastructure
+==============
+
+The infrastructure for providing the favicons essentially consists of three
+parts:
+
+- :py:obj:`Favicons-Proxy <.favicons.proxy>` (aka *proxy*)
+- :py:obj:`Favicons-Resolvers <.favicons.resolvers>` (aka *resolver*)
+- :py:obj:`Favicons-Cache <.favicons.cache>` (aka *cache*)
+
+To protect the privacy of users, the favicons are provided via a *proxy*.  This
+*proxy* is automatically activated with the above activation of a *resolver*.
+Additional requests are required to provide the favicons: firstly, the *proxy*
+must process the incoming requests and secondly, the *resolver* must make
+outgoing requests to obtain the favicons from external sources.
+
+A *cache* has been developed to massively reduce both, incoming and outgoing
+requests.  This *cache* is also activated automatically with the above
+activation of a *resolver*.  In its defaults, however, the *cache* is minimal
+and not well suitable for a production environment!
+
+.. _favicon cache setup:
+
+Setting up the cache
+====================
+
+To parameterize the *cache* and more settings of the favicons infrastructure, a
+TOML_ configuration is created in the file ``/etc/searxng/favicons.toml``.
+
+.. code:: toml
+
+   [favicons]
+
+   cfg_schema = 1   # config's schema version no.
+
+   [favicons.cache]
+
+   db_url = "/var/cache/searxng/faviconcache.db"  # default: "/tmp/faviconcache.db"
+   LIMIT_TOTAL_BYTES = 2147483648                 # 2 GB / default: 50 MB
+   # HOLD_TIME = 5184000                            # 60 days / default: 30 days
+   # BLOB_MAX_BYTES = 40960                         # 40 KB / default 20 KB
+   # MAINTENANCE_MODE = "off"                       # default: "auto"
+   # MAINTENANCE_PERIOD = 600                       # 10min / default: 1h
+
+:py:obj:`cfg_schema <.FaviconConfig.cfg_schema>`:
+  Is required to trigger any processes required for future upgrades / don't
+  change it.
+
+:py:obj:`cache.db_url <.FaviconCacheConfig.db_url>`:
+  The path to the (SQLite_) database file.  The default path is in the `/tmp`_
+  folder, which is deleted on every reboot and is therefore unsuitable for a
+  production environment.  The FHS_ provides the folder  for the
+  application cache
+
+  The FHS_ provides the folder `/var/cache`_ for the cache of applications, so a
+  suitable storage location of SearXNG's caches is folder ``/var/cache/searxng``.
+  In container systems, a volume should be mounted for this folder and in a
+  standard installation (compare :ref:`create searxng user`), the folder must be
+  created and the user under which the SearXNG process is running must be given
+  write permission to this folder.
+
+  .. code:: bash
+
+     $ sudo mkdir /var/cache/searxng
+     $ sudo chown root:searxng /var/cache/searxng/
+     $ sudo chmod g+w /var/cache/searxng/
+
+:py:obj:`cache.LIMIT_TOTAL_BYTES <.FaviconCacheConfig.LIMIT_TOTAL_BYTES>`:
+  Maximum of bytes stored in the cache of all blobs.  The limit is only reached
+  at each maintenance interval after which the oldest BLOBs are deleted; the
+  limit is exceeded during the maintenance period.
+
+  .. attention::
+
+     If the maintenance period is too long or maintenance is switched
+     off completely, the cache grows uncontrollably.
+
+SearXNG hosters can change other parameters of the cache as required:
+
+- :py:obj:`cache.HOLD_TIME <.FaviconCacheConfig.HOLD_TIME>`
+- :py:obj:`cache.BLOB_MAX_BYTES <.FaviconCacheConfig.BLOB_MAX_BYTES>`
+
+
+Maintenance of the cache
+------------------------
+
+Regular maintenance of the cache is required!  By default, regular maintenance
+is triggered automatically as part of the client requests:
+
+- :py:obj:`cache.MAINTENANCE_MODE <.FaviconCacheConfig.MAINTENANCE_MODE>` (default ``auto``)
+- :py:obj:`cache.MAINTENANCE_PERIOD <.FaviconCacheConfig.MAINTENANCE_PERIOD>` (default ``6000`` / 1h)
+
+As an alternative to maintenance as part of the client request process, it is
+also possible to carry out maintenance using an external process. For example,
+by creating a :man:`crontab` entry for maintenance:
+
+.. code:: bash
+
+   $ python -m searx.favicons cache maintenance
+
+The following command can be used to display the state of the cache:
+
+.. code:: bash
+
+   $ python -m searx.favicons cache state
+
+
+.. _favicon proxy setup:
+
+Proxy configuration
+===================
+
+Most of the options of the :py:obj:`Favicons-Proxy <.favicons.proxy>` are
+already set sensibly with settings from the :ref:`settings.yml <searxng
+settings.yml>` and should not normally be adjusted.
+
+.. code:: toml
+
+   [favicons.proxy]
+
+   max_age = 5184000             # 60 days / default: 7 days (604800 sec)
+
+
+:py:obj:`max_age <.FaviconProxyConfig.max_age>`:
+  The `HTTP Cache-Control max-age`_ response directive indicates that the
+  response remains fresh until N seconds after the response is generated.  This
+  setting therefore determines how long a favicon remains in the client's cache.
+  As a rule, in the favicons infrastructure of SearXNG's this setting only
+  affects favicons whose byte size exceeds :ref:`BLOB_MAX_BYTES <favicon cache
+  setup>` (the other favicons that are already in the cache are embedded as
+  `data URL`_ in the :py:obj:`generated HTML <.favicons.proxy.favicon_url>`,
+  which can greatly reduce the number of additional requests).
+
+.. _register resolvers:
+
+Register resolvers
+------------------
+
+A :py:obj:`resolver <.favicon.resolvers>` is a function that obtains the favicon
+from an external source.  The resolver functions available to the user are
+registered with their fully qualified name (FQN_) in a ``resolver_map``.
+
+If no ``resolver_map`` is defined in the ``favicon.toml``, the favicon
+infrastructure of SearXNG generates this ``resolver_map`` automatically
+depending on the ``settings.yml``.  SearXNG would automatically generate the
+following TOML configuration from the following YAML configuration:
+
+.. code:: yaml
+
+   search:
+     favicon_resolver: "duckduckgo"
+
+.. code:: toml
+
+   [favicons.proxy.resolver_map]
+
+   "duckduckgo" = "searx.favicons.resolvers.duckduckgo"
+
+If this automatism is not desired, then (and only then) a separate
+``resolver_map`` must be created.  For example, to give the user two resolvers to
+choose from, the following configuration could be used:
+
+.. code:: toml
+
+   [favicons.proxy.resolver_map]
+
+   "duckduckgo" = "searx.favicons.resolvers.duckduckgo"
+   "allesedv" = "searx.favicons.resolvers.allesedv"
+   # "google" = "searx.favicons.resolvers.google"
+   # "yandex" = "searx.favicons.resolvers.yandex"
+
+.. note::
+
+   With each resolver, the resource requirement increases significantly.
+
+The number of resolvers increases:
+
+- the number of incoming/outgoing requests and
+- the number of favicons to be stored in the cache.
+
+In the following we list the resolvers available in the core of SearXNG, but via
+the FQN_ it is also possible to implement your own resolvers and integrate them
+into the *proxy*:
+
+- :py:obj:`searx.favicons.resolvers.duckduckgo`
+- :py:obj:`searx.favicons.resolvers.allesedv`
+- :py:obj:`searx.favicons.resolvers.google`
+- :py:obj:`searx.favicons.resolvers.yandex`
