Can't load compression module

[Jimmy Stuart]

I'm running SP2 (actually the 1316 build) and I tried to implement the new compression module but it keeps saying that it can't be found.  I've rebuilt the project, verified the right DLL is in the folder etc.  This is occuring on the VS2008 webserver but the site itself is running IIS6.  Any ideas?

Configuration Error

Hi,

The declaration changed in the latest release.

Use <add name="RadCompression" type="Telerik.Web.UI.RadCompression" /> instead.

Thanks that was it.  I had payed attention to the blog post from December that multiple Telerik folks pointed us to as to how to use it.  Guess somebody forgot to update it.

Thanks for the update, I looked at the same blog entry also.

Now that my app is finding the module I am getting the following error.

Any ideas? I realise that this is a new feature and possibly isn't ready to be fully utilised yet but I have been looking for a way to compress the AJAX requests for a while now and expect that it will yield considerably better performance on some requests.

Thanks

Hello Damien,

From the stack trace of the exception it seems that due to some reason RadCompression module cannot execute its Compress method (its instance is not initialized). To progress in our investigation, is it possible for you to isolate a test case, illustrating the abnormality, and send it enclosed to a formal support ticket? We will test/debug it locally and will get back to you with our findings.

Additionally, verify that you are using the latest release 2008.3.1314 of RadControls for ASP.NET AJAX (Q3 2008 SP2).

Hi,
we have a similar problem. There is no problem to run our software on IIS 6.0, but we get the error message on another server. This server has the following components: Windows Server 2008 with IIS 7.0 and MOSS 2007

We think the MOSS-part is not the reason of our problem. Maybe there are changes in the structure of the IIS. Any Ideas?

Thanks in advance.

Hello Christian,

Could you specify what is the error you receive? Generally you should have no problems running applications with RadCompression on IIS7.

Kind regards,

Hi,
our error messages are in german, because we use the localized version of the operating system.

Any hints are welcome.

Hello Christian,

We are really not sure why you receive this error. Can you confirm your web.config has all the necessary references? The following help article elaborates on this:
