Ahmmm, there seems to be some kind of deep misunderstanding going on here. Response headers are sent from the server to the client and that client is usually a browser like IE, FF, Chrome etc.. Headers only make sense if the receiving party can interpret it correctly. When you are sending a Response.Redirect and also set some header like test, the browser will not forward this header to the site it is now redirecting to. If you are absolutely bent on passing some parameter to the site the browser will redirect to, you will have to pass that parameter as an URL parameter.

Similarily a Request header is some information the browser uses to pass back information about the current request to the server. This information will be used on the server to interpret the request correctly.

If you have any doubts, leave me a comment and I'll try to explain further.

I have a requirement similar to the original poster which I am really struggling with so any help would be really appreciated. I have to pass a token (string) in a HTTP request header to a 3rd party web application. In order to set up a test environment I create 2 ASP.Net websites, 1 which is my website which will set the HTTP request header value and the other which is simulating the 3rd party web application which will receive the HTTP request header. I have successfully set the request header on my website and verified this using the code below. I then perform a Response.Redirect to the simulated 3rd party web application which also uses the code below to determine if the token request header was received. Unfortunately the token request header is never displayed on the simulated 3rd party web application. I believe that I am setting the request header correctly so I feel that the problem is either with the way that I am attempting to transfer it to the simulated 3rd party web application or perhaps the request header is being sent to the simulated 3rd party web application but the way that I am checking for it is incorrect. I will be really grateful for any help or advice on this challenge. Here is the code I referred to earlier: headers = Request.Headers; for (int i = 0; i < headers.Count; i++) { string key = headers.GetKey(i); string value = headers.Get(i); Response.Write(key + " = " + value + " "); }

you should create a WCF application and need to expose that service. In WCF you can coustmize header and data part separatly.
<form action="" id="test" method="GET"></form>

<script type="text/javascript">

If you need to trigger that from a code behind, that can be done too:

Response.Write( @"<form action="" id="test" method="GET"></form>

<script type="text/javascript">
</script> ");

Is the above code secure?
