Issue with resource file in IIS 7

[Adonis]

I am having an issue with Ajax post-backs on some pages when I am on a page that is using URL rewrite for example
http://www.myajaxsite.com/admin/ the Ajax post-backs such as Radgrid filtering do not work but if I type in the full URL http://www.myajaxsite.com/admin/default.aspx then all is fine.

Does something need to change in the Web.config handlers for this to work properly?

Hello Adonis,

Note that when RadCompression is enabled and you are using .NET 4.0, event handlers might not be raised in a default document in IIS 7 or IIS 7.5 Integrated Mode. This problem is caused by a breaking change in .NET 4.0 described here. To workaround it one can set preCondition="managedHandler" for the RadCompression module. You may also need to remove the runAllManagedModulesForAllRequests setting from your web.config if you have it (or set it to false).

I hope this helps.

Kind regards,
Martin

I have made the suggested changes, it does not seem to make a difference in the way the application is responding

[NullReferenceException]: Object reference not set to an instance of an object.<br> 
 at Telerik.Web.UI.RadCompression.Compress(HttpApplication application)<br>  
at Telerik.Web.UI.RadCompression.PreRequestHandlerExecute(Object sender, EventArgs e)<br>  
at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()<br> 
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)<br>

Works fine if the URL is pointing to the full path.  Http://mywebapp/admin/default.aspx  VS. just Http://mywebapp/admin/

I was able to resolve the issue with the following section in web config

<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 enablePostbackCompression="true">  
    <excludeHandlers>         
      <add handlerPath="" matchExact="false" />         
    </excludeHandlers>  
  </radCompression>  
</telerik.web.ui>


Again thanks for your help
