@ -580,3 +580,35 @@ the maximum user-defined router priority value is:

### <EntryPoint>.Transport.RespondingTimeouts.<Timeout>
Starting with `v2.11.1` the following timeout options are deprecated:
- `<entryPoint>.transport.respondingTimeouts.readTimeout`
- `<entryPoint>.transport.respondingTimeouts.writeTimeout`
- `<entryPoint>.transport.respondingTimeouts.idleTimeout`
They have been replaced by:
- `<entryPoint>.transport.respondingTimeouts.http.readTimeout`
- `<entryPoint>.transport.respondingTimeouts.http.writeTimeout`
- `<entryPoint>.transport.respondingTimeouts.http.idleTimeout`
### <EntryPoint>.Transport.RespondingTimeouts.TCP.LingeringTimeout
Starting with `v2.11.1` a new `lingeringTimeout` entryPoints option has been introduced, with a default value of 2s.
The lingering timeout defines the maximum duration between each TCP read operation on the connection.
As a layer 4 timeout, it applies during HTTP handling but respects the configured HTTP server `readTimeout`.
This change avoids Traefik instances with the default configuration hanging while waiting for bytes to be read on the connection.
We suggest to adapt this value accordingly to your situation.
The new default value is purposely narrowed and can close the connection too early.
Increasing the `lingeringTimeout` value could be the solution notably if you are dealing with the following errors:
- TCP: `Error while handling TCP connection: readfrom tcp X.X.X.X:X->X.X.X.X:X: read tcp X.X.X.X:X->X.X.X.X:X: i/o timeout`
- HTTP: `'499 Client Closed Request' caused by: context canceled`
- HTTP: `ReverseProxy read error during body copy: read tcp X.X.X.X:X->X.X.X.X:X: use of closed network connection`
