Question

Using HttpClient from NuGet.

The app sends a post with client.PostAsync(). I’d like it to NOT follow 302 redirects.

how?

I figure I can just set AllowAutoRedirect as described in this answer.

But how do I get the HttpWebRequest used within a PostAsync() call?

Answer 1

One of the overloads of the HttpClient constructor takes a
WebRequestHandler argument. The HttpClient class uses this
WebRequestHandler for sending requests.

The WebRequestHandler class provides a property called AllowAutoRedirect
to configure the redirect behaviour. Setting this property to false
instructs the HttpClient to not follow redirect responses.

Here is a small code sample:

WebRequestHandler webRequestHandler = new WebRequestHandler();

webRequestHandler.AllowAutoRedirect = false;

HttpClient httpClient = new HttpClient(webRequestHandler);

// Send a request using GetAsync or PostAsync

Task<HttpResponseMessage> response = httpClient.GetAsync("http://www.google.com");
