Some demos:

* https://latest.datasette.io/fixtures/facetable now no longer redirects to the hash
* https://latest.datasette.io/fixtures/facetable?_hash=1 redirects to https://latest.datasette.io/fixtures-dd88475/facetable

There are now three config settings relevant to the above:

`default_cache_ttl` - defaults to 5s. The default cache TTL for non-hashed resources.
`default_cache_ttl_hashed` - defaults to 31536000s. The default cache TTL for hashed resources.
`hash_urls` - defaults to False. If True, all URLs will attempt to redirect to their hashed version.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",421548881,
