  hi,
  
  im using radcompression to compress my wcf ria requests but im having error. when i use fiddler, it says, the reported size doesnt match the actual size being sent? i suppose this becuase of the compression but it should match right.
  
  is there anything wrong in my implementation? i just copy the Telerik.Web.UI.dll in my servers bin folder. then add in webconfig's httpmodules. anything else?
  
  thank you!

  Hello Adrian,
  
  Can you please verify that you are using RadControls for ASP.NET AJAX latest internal build, as the current official version (Q1 2010 SP2) of RadCompression does not support official version of WCF RIA services.
  
  If you continue to experiencing difficulties, please consider providing (through a formal support ticket) a small runnable project in which this behavior can be observed. This way we will be able to debug it locally and provide you with more to- the-point answer.
  
  Kind regards,
  Rosen

  This problem is very easy to duplicate. Just create a WcfService using the template provided by VS 2010 then enable RadCompression in web.config. The WCF calls will start returning a content-type mismatch.
  
  I will provide a working (or non-working) sample via a ticket, but I'm wondering if the problem has already been fixed in the internal build and, if so, when the next release or SP will be available?
  
  Thanks,
  Scott

  Hello Scott,
  
  Indeed we are aware of this behavior.This unwanted behavior is replicated only when using IE and VS2010 build-in web server set to run on .NET4.0. The same page runs ok in FireFox and in IE if ran on IIS7.5 with .NET 4.0 pool or on integrated web server under .NET 2.0/3.5.
  
  Unfortunately we need further investigations. As temporary solution you can exclude the service from being compressed.
  

  <configuration>

  ...

    <configSections>

      <sectionGroup name="telerik.web.ui">

        <section name="radCompression" type="Telerik.Web.UI.RadCompressionConfigurationSection, Telerik.Web.UI, PublicKeyToken=121fae78165ba3d4" allowDefinition="MachineToApplication" requirePermission="false"/>

      </sectionGroup>

    </configSections>

    <telerik.web.ui>

      <radCompression>

        <excludeHandlers>

          <add handlerPath="Service.svc" matchExact="false"/>

        </excludeHandlers>

      </radCompression>

    </telerik.web.ui>

  ....

  Thanks for the info Nikolay. I had disabled all RadCompression, but excluding just the service is better. Thanks for the tip!

  I too am experiencing this issue and it doesn't appear to have been fixed for the Q3 2010 release.  I have some extra information that might help Telerik resolve this issue.
  
  I am using a WCF service that sends the bytes of a .docx file to the new RadRichTextBox.  I have tested the 4 permutations of IIS6/7 vs. Compression on/off and it appears that the bug with RadCompression lies in using IIS 6.
  
  IIS 6 + RadCompression ON = Failure, size mismatch. HTTP Header says to expect a size of 33,635 bytes where the actual size returned is 34,549 bytes.  Something somewhere in my code fails at that point, I have not dug into that
  
  IIS 6 + RadCompression OFF = Success.  HTTP Header and actual size match at 33,635
  
  IIS 7 + RadCompression ON = Success. HTTP Header = 34,812, actual is the same.
  
  IIS 7 + RadCompression OFF = Success. HTTP Header = 33,635, actual is the same
  
  --Tested using IIS 6 (Windows Sever 2003) and IIS 7.5 (Windows 7) both with .NET 4 using .NET 4 app pools.

  Hello Kevin,
  
  This is known behavior so far. You can find the issue logged in MS Connect and keep track of its status:
