Can i use Radupload / handlers and progress to upload files in a cross domain scenario?

Thanks

Hi,

The attached sample, shows how to upload files in cross domain scenarios with RadAsyncUpload. The sample contains two websites -Web1 and Web2. The Web1 is the website that contains the custom handler. It is configured to accept cross domain requests: 

<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Headers" value="Origin,cache-control,content-type,man,messagetype" />
  </customHeaders>
</httpProtocol>

and should be hosted on the file server, where the files will be uploaded. Note that on this server you must have temporary folder, which is the same as configured in the Web2: 

<telerik:RadAsyncUpload
    ID="RadAsyncUpload1"
    DisablePlugins="true"
    TemporaryFolder="C:\\Temp\"
    EnablePermissionsCheck="false"
    runat="server">
</telerik:RadAsyncUpload>

The second site Web2 will transfer selected files directly to the handler of the Web1.

Hi Hristo,

I tried your solution and it works fine in all browsers except of IE9 and bellow versions of IE.
I have unheralded javascript exception in the browsers.
As I understand from your javascript code, there is problem with iFrame access.
I have such structure:
Handler on - subdomain1.test.com
Web site with control on -  subdomain2.test.com
Could you please help me with the problem?

Best Regards,
Yuri

I found some workaround for the problem. I described it on my blog: http://tech.panshin.me/development/telerik-cross-domain-radasyncupload.html
