Hi, Check below example.<br />
<br />

<pre><code class="code-10 nolinks" id="code-20-41500352-1"><span>public void ProcessRequest(HttpContext context)</span>
<span>        {</span>
<span>            string []header = context.Request.Headers.AllKeys;</span>
<span>            if (!header.Contains(&quot;name&quot;))</span>
<span>            {</span>
<span>                context.Response.ContentType = &quot;text/plain&quot;;</span>
<span>                context.Response.Write(&quot;Please send name in request header&quot;);</span>
<span>            }</span>
<span>            else</span>
<span>            {</span>
<span>                string name = context.Request.Headers.Get(&quot;name&quot;);</span>
<span>                context.Response.ContentType = &quot;text/plain&quot;;</span>
<span>                context.Response.Write(&quot;Hi &quot; + name + &quot;! Thanks to send name in HTTP header&quot;);</span>
<span>            }</span>
<span>        }</span>

@Manoj: Thank you, my question is, when this runs/executes, where should I see the message on the screen? Do I need to look in the firbug (or other) debugger, or should it show directly on the page? Right now I'm not seeing anything and just want to make sure I'm looking in the right place.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.
