How to dump ASP.NET Request headers to string

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 Reque

Answer 1

You can use,

string headers = Request.Headers.ToString(); 

But It will return URL encoded string so to decode it use below code,

String headers = HttpUtility.UrlDecode(Request.Headers.ToString()) 

Answer 2

You could turn on tracing on the page to see headers, cookies, form variables, querystring etc painlessly:

Top line of the aspx starting:

<%@ Page Language="C#" Trace="true" 

Answer 3

You can get all headers as string() in one shot, using this (VB.Net)

Request.Headers.ToString.Split(New String() {vbCrLf}, StringSplitOptions.RemoveEmptyEntries)

Answer 4

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
