How to add and access Custom Header in C#

Question

Hi

I need to add a custom header something like MYName: Balaji which i need to access from .aspx file through Request.ServerVariables["HTTP_MYName"]; should return "Balaji". I need so many variables like this it will added dynamically. Kindly help.

Also, I cannot persist this varaibles in any of the .Net controls or objects like cookies, sessions, application, hidden variable etc., or cannot store this in d/b and get it back whenever is required, I NEED IT ONLY IN HTTP HEADERS.

Kindly send the C# code how to add this variable and get the value back in .aspx file.

What do you mean by "get the value back in .aspx file"? HTTP headers are intended to be used as directives to a browser, how to interpret the given content. You don't have access to these values in your document.

Setting a custom HTTP header is quite easy, however:

   Page.Response.AddHeader("MyCustomHeader", "VerySecretValue")

Updated my answer as per your comment. If you need to transfer information between a HTTPModule and an ASPX page, you can use HTTPContext.Current, since this stays the same in both places. So, you add it by

  HttpContext.Current.Items.Add("SecretKey", "SecretValue");

and read it as

  string s = HttpContext.Current.Items["SecretKey"];
