1148725876 I_kwDOBm6k_c5EeCp0 1640 Support static assets where file length may change, e.g. logs 57859326 open 0     2 2022-02-24T00:34:42Z 2022-03-05T01:19:25Z   NONE  

This is a bit of an oxymoron.

I am serving a log.txt file for a background process using the Datasette --static CLI. This is useful as I can observe a background process from the web UI to see any errors that occur (instead of spelunking the logs via docker exec/ssh etc).

I get this error, which I think is because Datasette assumes that the size of the content does not change (but appending new log lines means the content length changes).

Thanks, I am finding Datasette very useful.
