ETag
(entity tag) and last-modified timestamp as determined by
the application. Also transparently prepares the response, setting HTTP
status, and adding "ETag" and "Last-Modified" headers when applicable.
This method works with conditional GET/HEAD requests as well as with
conditional POST/PUT/DELETE requests.
Note: The HTTP specification recommends setting both
ETag and Last-Modified values, but you can also use
#checkNotModified(String)
or
ServerWebExchange.checkNotModified(Instant)
.
