 # Providing your own HttpClient and proxy using MSAL.NET
 When [initializing a client application](msal-net-initializing-client-applications.md), you can use the `.WithHttpClientFactory method` to provide your own HttpClient.  Providing your own HttpClient enables advanced scenarios such fine-grained control of an HTTP proxy, customizing user agent headers, or forcing MSAL to use a specific HttpClient (for example in ASP.NET Core web apps/APIs).
 
+`HttpClient` is intended to be instantiated once and then reused throughout the life of an application. See [Remarks](/dotnet/api/system.net.http.httpclient?view=net-5.0#remarks).

 ## Initialize with HttpClientFactory
 The following example shows to create an `HttpClientFactory` and then initialize a public client application with it:

 ## HttpClient and Xamarin iOS
 When using Xamarin iOS, it is recommended to create an `HttpClient` that explicitly uses the `NSURLSession`-based handler for iOS 7 and newer. MSAL.NET automatically creates an `HttpClient` that uses `NSURLSessionHandler` for iOS 7 and newer. For more information, read the [Xamarin iOS documentation for HttpClient](/xamarin/cross-platform/macios/http-stack).
