Is it possible to add response http headers in web.config?

Question

In my application I need to set a http response header. I'd like to do this in web.config.

Answer 1

The best way to do this would be the <customHeaders> element of the web.config file. Note that this only works for IIS version 7 and above.

The configuration to add your example header would be:

<configuration>   <system.webServer>     <httpProtocol>       <customHeaders>         <add name="Content-Language" value="*" />       </customHeaders>     </httpProtocol>   </system.webServer> </configuration> 

For more information see the IIS "Custom Headers" Configuration Reference page

Answer 2

Solution Finally, after a long search I found the solution. Create a class with this code:

public class myHTTPHeaderModule : IHttpModule {      #region IHttpModule Members      public void Dispose()     {      }      public void Init(HttpApplication context)     {         context.EndRequest += new EventHandler(context_EndRequest);     }      void context_EndRequest(object sender, EventArgs e)     {         HttpResponse response = HttpContext.Current.Response;          response.AddHeader("Content-Language", "*");      }      #endregion } 

(Don't ask me why to use this event, but it works..)

Now add a line in web.config in the HttpModule section:

    <httpModules>         <add type="namespace.myHTTPHeaderModule, assembly name" name="headers" />         <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>     </httpModules> 

And that's it!
