Custom IHttpHandler

Alfred Brockotter asked on February 20, 2014 10:24

Hello Guys,

I'm new to kentico (just working with kentico 7 for 3 weeks now) and i have a question about implementing a custom HttpHandler.

What i have done so far: I've created a new class library and created a httphandler:

public class SpelenHandler : IHttpHandler
        /// <summary>
        /// You will need to configure this handler in the web.config file of your 
        /// web and register it with IIS before being able to use it. For more information
        /// see the following link:
        /// </summary>
        #region IHttpHandler Members

        public bool IsReusable
            // Return false in case your Managed Handler cannot be reused for another request.
            // Usually this would be false in case you have some state information preserved per request.
            get { return true; }

        public void ProcessRequest(HttpContext context)
            context.Response.ContentType = "application/json";
            // prepare the user's ID
                int gameId = 0;

                int.TryParse(context.Request.QueryString["gameid"].ToString(), out gameId);

                // get the object from database according to the data class name and ID
                IDataClass gameObj = DataClassFactory.NewDataClass("Custom.Game", gameId);
                // acquire the user's name
                int TimesPlayed = Convert.ToInt32(gameObj.GetValue("TimesPlayed").ToString());
                TimesPlayed = TimesPlayed + 1;
                // change the user's full name
                gameObj.SetValue("TimesPlayed", TimesPlayed);
                // update the database record


            catch {


I registered that handler in IIS and adjusted the web.config of my kentico instance. Now i am able to send jquery ajax requests to my handler and update my documenttype. This works perfectly! But a big disadvantage is compiling it against different versions of kentico (because of the reference to CMS.DataEngine.dll etc).

So therefor:

  1. Is it possible to define this httphandler inside the app_code of kentico?

  2. And what other options do i have for sending/recieving json ajax requests to/from the "backend"? I played already a bit with the service.asmx but i don't like that to much because it depends on the AjaxControlToolkit.

Kind regards, Alfred

  1. Yes, you can add your code to App_Code as usual
  2. You can use e.g. PageMethod or any other services. There is nothing special about it. Or, you can also use the REST services.
