RadCompression issues.

[Sean]

Hello Telerik,

I am re-visiting RadCompression for my web application. I had attempted to implement RadCompression preivously, but encountered issues. I have attempted to re-implement RadCompression, but am still encountering issues, so I am here. :)

So, first off, a bit of information about my working environment. The solution I am working in is broken into two parts. The main architecture is ASP.NET MVC 2.0. There is a portion of the solution that is ASP.NET AJAX. It's all targeting 4.0 framework.

The ASP.NET AJAX portion of my web application contains all Telerik controls. I have not experienced any issues using the Telerik controls in this manner. 

Now, I have just gone through http://www.telerik.com/help/aspnet-ajax/radcompression.html and followed the step-by-step instructions on how to implement rad compression. In my Web.Config file I have the following entries:

    <httpModules>
        <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
         <add name="RadCompression" type="Telerik.Web.UI.RadCompression" />
    </httpModules>
</system.web>

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules runAllManagedModulesForAllRequests="true">
        <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
         <add name="RadCompression" type="Telerik.Web.UI.RadCompression"/>
    </modules>

Under the latest version of Google Chrome I do not encounter any issues.
Under the latest version of Opera I do not encounter any issues.
Under the latest version of Internet Explorer I experience only minor issues. One of our web services is unable to be loaded with RadCompression enabled. I am (relatively) confident that with some time I could set up the proper exclusionary rules to make this a non-issue.

That's about where the good news ends. Under the latest version of FireFox I am presented with an (presumed) uncompressed stream of data. It looks like this:

The latest version of Safari follows suit and presents me with the garbage text, as well.

What steps should I be taking to debug this issue? What are common scenarios which would cause these issues?

Just as additional information...here is my RegisterRoutes method inside of Global.asax.cs. In addition, I have included the entirety of my web.config to this thread. It's a large-ish file, but I thought it might be useful in answering my questions.

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    routes.IgnoreRoute("ChartImg.axd/{*pathInfo}");
    routes.IgnoreRoute("{controller}/ChartImg.axd/{*pathInfo}");
    routes.IgnoreRoute("{controller}/{action}/ChartImg.axd/{*pathInfo}");

    routes.MapRoute("Components", "Component/Index/{ID}", new {controller = "Component", action = "Index", id = ""});

    routes.MapRoute(
        "Default",                                              // Route name
        "{controller}/{action}/{ID}",                           // URL with parameters
        new { controller = "LogIn", action = "Index", id = "" }  // Parameter defaults
    );

    routes.MapRoute(
        "Root",
        "",
        new { controller = "Home", action = "Index", id = "" }
    );
}

Hi,

It looks like a firefox issue. Have you checked that you have gzip compression enabled for firefox?

Thanks,
Hus

[Sean]

Hi Hus,

IMO, regardless of client-side configuration, this should not be the end result. If GZIP compression is not seen in the "Accepted Encoding" property of the browser's HTTP Header, then GZIP compression should not be applied. (Similarly with DEFLATE). I would expect no compression to be applied if the browser does not have compression enabled/allowed.

 Nevertheless, I've attached an image showing that my instance of FireFox is currently anticipating gzip/deflate encoded streams.

Hello Sean,

It is strange that you observe the issue in FF only. However I would suggest that you review your code and verify whether another type of compression is not enabled. Please also try to temporarily remove any code that changes the "Content-encoding" header of the response object. If none of these modifications work, I am afraid that I would need a runnable example that I could debug locally. This way I will be able to provide you with more to the point resolution.

Best wishes,
Martin

Hi Martin,

So I did a bit of looking through the entire solution, and I found the culprit, but I don't understand why this is the culprit -- or how to make things play nicely together. Hopefully your expertise can shed more light on the issue.

We have the following class which is applied to methods which return an ActionResult:

public class CompressionFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
            HttpRequestBase request = context.HttpContext.Request;

            string acceptEncoding = request.Headers["Accept-Encoding"];

            if (string.IsNullOrEmpty(acceptEncoding))
                return;

            acceptEncoding = acceptEncoding.ToUpperInvariant();

            HttpResponseBase response = context.HttpContext.Response;

            if (acceptEncoding.Contains("GZIP"))
            {
                response.AppendHeader("Content-encoding", "gzip");
                response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
            }
            else if (acceptEncoding.Contains("DEFLATE"))
            {
                response.AppendHeader("Content-encoding", "deflate");
                response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
            }
    }
}

It's not an option to remove this code... it would slow down the rest of our web application by a large factor -- and most of our web application does not use Telerik controls.

Is this a supported scenario?

EDIT: Oh, I got it. The problem was that there was double-encoding going on. I put the following code in to fix this issue:

if (!response.Headers.AllKeys.Contains("Content-encoding"))
{

 
This will check to see if the header has already been encoded (for my code). If it has ( by RadCompression ) then I won't put the header on again. This resolved the issue. Thanks for making me think of it!
