| 193 | Control HTTP caching with ?_ttl= | You can now customize the HTTP max-age header that is sent on a per-URL basis, using the new ?_ttl= query string parameter. You can set this to any value in seconds, or you can set it to 0 to disable HTTP caching entirely. Consider for example this query which returns a randomly selected member of the Avengers: select * from [avengers/avengers] order by random() limit 1 If you hit the following page repeatedly you will get the same result, due to HTTP caching: /fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1 By adding ?_ttl=0 to the zero you can ensure the page will not be cached and get back a different super hero every time: /fivethirtyeight?sql=select+*+from+%5Bavengers%2Favengers%5D+order+by+random%28%29+limit+1&_ttl=0 |
