@@ -172,3 +172,3 @@ If you want to use sticky sessions on a load balancer level as an optimimization for Centrifugal bidirectional emulation layer keep in mind that we currently use `same-origin` credentials policy for emulation requests in `http_stream` and `sse` transport cases. So cookies will only be passed in same-origin case. Please open an issue in case you need to configure more relaxed credentials. Though in most cases stickyness based on client's IP may be sufficient enough.
