You need to set: webRequest.Method = “HEAD”; This way the server will respond with the header information only (no content). This is also useful to check if the server accepts certain operations (i.e. compressed data etc.).
You can use ReadAsStringAsync() method, then get the result using await statement or Result property: StringContent sc = new StringContent(“Hello!”); string myContent = await sc.ReadAsStringAsync(); //or string myContent = sc.ReadAsStringAsync().Result;
I finally dug up the obscure command from MSDN that fixes this: ServicePointManager.DnsRefreshTimeout = 0; As I unwound all the weird things I’d tried previously, I discovered one other setting that I need along with the one above; on the request object, turn off keep-alive: request.KeepAlive = false;
The IPAddress class is not very friendly to serialization, as you’ve seen. Not only will it throw a SocketException if you try to access the ScopeID field for an IPv4 address, but it will also throw if you try to access the Address field directly for an IPv6 address. To get around the exceptions, you … Read more

Using .NET 4.5 (or .NET 4.0 by adding the Microsoft.Net.Http package from NuGet) there is an easier way to simulate form requests. Here is an example: private async Task<System.IO.Stream> Upload(string actionUrl, string paramString, Stream paramFileStream, byte [] paramFileBytes) { HttpContent stringContent = new StringContent(paramString); HttpContent fileStreamContent = new StreamContent(paramFileStream); HttpContent bytesContent = new ByteArrayContent(paramFileBytes); using … Read more
If you’re using the HttpClient class, then you’ll get a HttpResponseMessage back. This class has a useful property called IsSuccessStatusCode that will do the check for you. using (var client = new HttpClient()) { var response = await client.PostAsync(uri, content); if (response.IsSuccessStatusCode) { //… } } In case you’re curious, this property is implemented as: … Read more
The idiomatic usage of EnsureSuccessStatusCode is to concisely verify success of a request, when you don’t want to handle failure cases in any specific way. This is especially useful when you want to quickly prototype a client. When you decide you want to handle failure cases in a specific way, do not do the following. … Read more
::1 is the loopback address in IPv6. Think of it as the IPv6 version of 127.0.0.1. See http://en.wikipedia.org/wiki/Localhost
