Hi,

 

Are you using IIS7 integrated mode ?

 

if not , please also make sure you add them to <system.web/> (not system.webServer):

 

<system.web>

 <httpModules>
     <add name="CuteWebUI.UploadModule" type="CuteWebUI.UploadModule,CuteWebUI.AjaxUploader" />
 </httpModules>
 </system.web>

 

Regards,

Terry
