Merge e0a3dee3bf into 75c9de02d1

while PR #2357 [1] was being implemented the question came up:

    would be better to change the PING resource from CSS to an image so that
    some terminal based browser may still able to pass the test [1]

This patch implements a POC in where a <img src=token> tag is loaded instaed a
CSS.

To test this patch activate limiter and link_token method [3] and start a
developer instance::

    make run

In your terminal browser open http://127.0.0.1:8888/search?q=foo

If the browser is suitable for the link_token method, it loads the image and the
following messages appear::

    DEBUG   searx.botdetection.limiter    : OK 127.0.0.1/32: /clientft61aak7fzyu6o6v.svg ...
    DEBUG   searx.botdetection.link_token : token is valid --> True
    DEBUG   searx.botdetection.link_token : store ping_key for (client) network 127.0.0.1/32 (IP 127.0.0.1) -> SearXNG_limiter.ping[...]

Browsers that do not load images will be blocked: If you try by example::

    lynx http://127.0.0.1:8888/search?q=foo

you will see a WARNING message like::

    WARNING searx.botdetection.link_token : missing ping (IP: 127.0.0.1/32) / request: SearXNG_limiter.ping[...]

-
-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`

+  values defined in the runtime environment.
+
+All the SearXNG setups are centralized in the :ref:`settings.yml` file.  This

+*installed instance* on the server or the *installed developer instance* at

+Tasks running outside of an *installed instance*, especially :ref:`installation
+and maintenance <searxng maintenance>` tasks running at (pre-) installation time
+do not have access to the SearXNG setup (from a *installed instance*).  Those
+tasks need a *build environment*.

+from the YAML configuration:
+
+- ``SEARXNG_URL`` from :ref:`server.base_url <settings  server>` (aka
+  ``PUBLIC_URL``)
+- ``SEARXNG_BIND_ADDRESS`` from :ref:`server.bind_address <settings server>`
+- ``SEARXNG_PORT`` from :ref:`server.port <settings server>`
+
+The ``GIT_URL`` and ``GIT_BRANCH`` in the origin:`utils/brand.env` file, are
+read from the git VCS and the branch that is checked out when ``make
+buildenv`` command runs.
+
+.. _brand:
+
+**I would like to create my own brand, how should I proceed?**
+
+Create a remote branch (``example.org``), checkout the remote branch (on your

+:ref:`settings server` section set ``base_url``.  Run ``make buildenv`` and
+create a commit for your brand.
+
+On your server you clone the branch (``example.org``) into your HOME folder
+``~`` from where you run the :ref:`installation <installation>` and
+:ref:`maintenance <searxng maintenance>` task.
+
+To upgrade you brand, rebase on SearXNG's master branch (on your local

+Limiter
+=======
+
+.. sidebar:: info
+
+   The limiter requires a :ref:`Redis <settings redis>` database.
+
+Bot protection / IP rate limitation.  The intention of rate limitation is to
+limit suspicious requests from an IP.  The motivation behind this is the fact
+that SearXNG passes through requests from bots and is thus classified as a bot
+itself.  As a result, the SearXNG engine then receives a CAPTCHA or is blocked
+by the search engine (the origin) in some other way.
+
+To avoid blocking, the requests from bots to SearXNG must also be blocked, this
+is the task of the limiter.  To perform this task, the limiter uses the methods
+from the :py:obj:`searx.botdetection`.
+
+To enable the limiter activate:
+
+.. code:: yaml
+
+   server:
+     ...
+     limiter: true  # rate limit the number of request on the instance, block some bots
+
+and set the redis-url connection. Check the value, it depends on your redis DB
+(see :ref:`settings redis`), by example:
+
+.. code:: yaml
+
