cache 302 redirects to farm much longer
Currently the redirects from the archive to the farm are cached for just 600 seconds, putting a lot of load on the flask app. The artifacts the redirects point to are cached much longer, though. By that, we still see a lot of load on the flask app, which finally needs to be rate-limited.
By introducing a new parameter CACHE_TIMEOUT_ARCHIVE_REDIRECT to control the max-age of the redirects, we can make these requests also cacheable. Currently we use a max-age of 1 day, but this can be fine-tuned later on.
