All favicons implementations have been documented and moved to the Python
package:
searx.favicons
There is a configuration (based on Pydantic) for the favicons and all its
components:
searx.favicons.config
A solution for caching favicons has been implemented:
searx.favicon.cache
If the favicon is already in the cache, the returned URL is a data URL [1]
(something like `data:image/png;base64,...`). By generating a data url from
the FaviconCache, additional HTTP roundtripps via the favicon_proxy are saved:
favicons.proxy.favicon_url
The favicon proxy service now sets a HTTP header "Cache-Control: max-age=...":
favicons.proxy.favicon_proxy
The resolvers now also provide the mime type (data, mime):
searx.favicon.resolvers
