 ## Best practices for HTTP connections
 
-The .NET SDK uses `HttpClient` to perform HTTP operations for both data plane for Gateway mode and [metadata for Direct mode](sdk-connection-modes.md#direct-mode). One of the [fundamentals of HttpClient](/dotnet/fundamentals/networking/http/httpclient-guidelines#dns-behavior) is to make sure the `HttpClient` can react to DNS changes on your account by **customizing the pooled connection lifetime**. As long as pooled connections are kept open, they do not react to DNS changes.  This setting forces pooled **connections to be closed** periodically, ensuring that your application reacts to DNS changes. Our recommendation is that you customize this value according to your [connectivity mode](sdk-connection-modes.md) and workload to balance the performance impact of frequently creating new connections, with needing to react to DNS changes (a 5 minute value would be a good start for Direct mode clients).
+The .NET SDK uses `HttpClient` to perform HTTP requests regardless of the connectivity mode configured. In [Direct mode](sdk-connection-modes.md#direct-mode) HTTP is used for metadata operations and in Gateway mode it is used for both data plane and metadata operations.

 You can inject your custom HttpClient through `CosmosClientOptions.HttpClientFactory`, for example:
