RadCompression causing the page Methods to file in iis7 classic mode

[dipen shah]

We are using windows8 r2 , IIS7.5 and web site is configured to use classic mode instead of Integrated mode. We have issues with Page methods failing when we use RadCompression in HttpModules. But the same setup works fine with integrated mode.

Here is the error message:

HTTP Post used to access the path "webform1.aspx\PageMethodTest" is not allowed.

Page methods are working fine when we remove the RadCompression from the web.config.
Any help how to resolve this issue with using RadCompression in classic mode ?
web.config  -

 

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

 <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules>
      <add name="RadCompression" type="Telerik.Web.UI.RadCompression"/>
    </modules>

Hello Dipen Shah,

I suspect that you have hit a know issue in the classic application pool in scenarios where IHttpModule filters the application response. The problem is already reported to Microsoft and you can follow its status here.

I hope this helps.

All the best,
