So, the correct way to handle a 409 response is to update your
X-Transmission-Session-Id and to resend the previous request.
2.3.2. DNS Rebinding Protection
If CSRF protection is enabled, additional check is being made on each RPC
request to make sure that the client sending the request does so using
one of the allowed hostnames by which RPC server is meant to be available.
If host whitelisting is enabled (which is true by default), Transmission
inspects the "Host:" HTTP header value (with port stripped, if any) and
matches it to one of the whitelisted names. Regardless of host whitelist
content, "localhost" and "localhost." domain names as well as all the IP
addresses are always implicitly allowed.
For more information on configuration, see settings.json documentation for
"rpc-host-whitelist-enabled" and "rpc-host-whitelist" keys.
