some configurations of nginx have been optimized recently
found that nginx will enable etag function by default, aiming at static files
so is it still useful to set it in server?
`
location ~. . (js | css)?. $
{
root /home/app/static;
expires 12h;
}
```
I try to comment out the configuration of cached static resources in server above
access the static js file of the server, which is still in a state of 304, with etag
attached. Please explain it clearly.
