There are various HTTP message handles that can be used. These include the following.
DelegatingHandler - A class used to plug a handler into a handler chain.
HttpMessageHandler - A simple class to derive from that supports the most common requirements for most applications.
HttpClientHandler - A class that operates at the bottom of the handler chain that actually handles the HTTP transport operations.
WebRequestHandler - A specialty class that operates at the bottom of the handler chain class that handles HTTP transport operations with options that are specific to the System.Net.HttpWebRequest object.
This is necessary since methods on HttpClient can be called concurrently and need a guarantee of thread safety. So if a handler is assigned to an HttpClient instance, the SendAsync method of the handler may get called concurrently by the HttpClient instance and needs to be thread safe.
Initializes a new instance of the HttpMessageHandler class.
Releases the unmanaged resources and disposes of the managed resources used by the HttpMessageHandler.
