Error in getting HTTP response custom Header

Question

I am trying to add a custom Headers -> e1 HttpContext.Current.Response.AddHeader("e1","example of an exception"); to HTTP response in Page_Load method which works fine as I checked it in chrome developer tools.

The problem is if I am trying to write the same response using : HttpContext.Current.Response.Write(HttpContext.Current.Response.Headers["ALL_HTTP"].ToString()); it causes an PlatformNotSupportedException : This operation requires IIS integrated pipeline mode.

So the main question is how to read the added response header given I am using the inbuilt VS development server?
And it would be great if you can suggest some articles or book to know about properly using HTTP headers and verbs.

Answer 1

If you want to write that variable directly to the response then you can simply call this in your Page_Load. This will avoid the IIS integrated pipeline mode requirement.

Page.Response.Write(Request.ServerVariables["ALL_HTTP"]);

For learning I would concentrate on learning about HTTP and REST.

• A fun primer on REST http://tomayko.com/writings/rest-to-my-wife
• HTTP: The Definitive Guide by David Gourley (solid book that will guide you from the simple HTTP protocol into more advanced concepts)
• HTTP 1.1 spec at http://www.w3.org/Protocols/rfc2616/rfc2616.html (dry read by the authority)
