I have a problem with the RadUpload Silverlight.
When I use the radupload in my local solution, all is OK.
When my silverlight application is deployed on a server with windows 2003 SP2 and IIS-6 with Windows Authentication (i can't change it, the application needs it ), I have an error :
Handler not found or execution of handler failed!
the server return : Notfound
So I've tried to inspect the http request with fiddler and then when the silverlight application access to the RadUploadHandler (ashx file) it return an error 401.2 which is a problem of authentication.
If I try the uri of the file .ashx in ie the response is normal :
{"JSONData":[{"Key":"RadUAG_message","Value":"Empty file name"},{"Key":"RadUAG_success","Value":false}]}
Could you help me to find the way to have authentication information when the radupload SL call the ashx.
Thanks
