What curl can do and Invoke-WebRequest can't do

• curl can show the raw request header and body with --trace option*1. There is no way to get the content of the request with Invoke-WebRequest.
• curl can show the body of 5xx response. Invoke-WebRequest returns null when a server responds with status 4xx or 5xx, so you cannot view the body of the response.
• curl shows the content of the 302 Found response when a server redirects the request. Invoke-WebRequest only shows the content of the 200 response in the same situation.
