Does HttpClient use HttpWebRequest?
HttpClient combines the flexibility of HttpWebRequest and WebClient. To start, we use the async and await keywords. HttpClient doesn’t support FTP, mocking and testing HttpClient is easier.
How is the behavior of the WebRequest class determined?
Because the WebRequest class is an abstract class, the actual behavior of WebRequest instances at run time is determined by the descendant class returned by Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.
Which is better httpclient or httpwebrequest for better performance?
HttpClient is preferred over HttpWebRequest due to async methods available out of the box and you would not have to worry about writing begin/end methods. Basically when you use async call (using either of the class), it will not block the resources waiting for the response and any other request would utilise the resources to make further calls.
What happens if you pass in a URL to httpwebrequest?
If you only pass in HTTP: URL’s, then the former code allows you to access the properties and methods the subclass HttpWebRequest implements in addition to those defined on the base class WebRequest. But if you passed in a FTP: URL then the attempt to cast to HttpWebRequest would fail.
Do you use the httpwebrequest constructor in System.Net?
Instead, use the System.Net.Http.HttpClient class. The HttpWebRequest class provides support for the properties and methods defined in WebRequest and for additional properties and methods that enable the user to interact directly with servers using HTTP. Do not use the HttpWebRequest constructor.
