Question

I’d like to email myself a quick dump of a GET request’s headers for debugging. I used to be able to do this in classic ASP simply with the Request object, but Request.ToString() doesn’t work. And the following code returned an empty string:

using (StreamReader reader = new StreamReader(Request.InputStream))
{
    string requestHeaders = reader.ReadToEnd();
    // ...
    // send requestHeaders here
}

Answer 1

Have a look at the Headers property in the Request object.

C#

string headers = Request.Headers.ToString();

Or, if you want it formatted in some other way:

string headers = String.Empty;
foreach (var key in Request.Headers.AllKeys)
  headers += key + "=" + Request.Headers[key] + Environment.NewLine;

VB.NET:

Dim headers = Request.Headers.ToString()

Or:

Dim headers As String = String.Empty
For Each key In Request.Headers.AllKeys
  headers &= key & "=" & Request.Headers(key) & Environment.NewLine
