Hi,

 I'm using RadAsyncUpload control. I'm using forms authentication in application.

When I log in and upload bigger pdf file(92 MB) it works but when i run a page which is used for guest users(user is not authenticated in this case). The same file does not upload there and throws error as below.(Files with less size like 3MB or 5 MB are getting uploaded on guest page without authentication ).

"NetworkError: 404 Not Found - http://MySite/Telerik.Web.UI.WebResource.axd?type=rau"​

uncaught exception: Error while uploading, HTTP Error code is: 404

 -------

Once I log in and upload, that works. But when I upload file from guest page which doesn't require authentication, I'm getting error.(I've used Form Authentication in my application)

I have added following in Web.Config already.

<location path="Telerik.Web.UI.WebResourceSession.axd">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
      <authentication mode="None" />
    </system.web>
  </location>

  <location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
      <authorization>
        <allow users="*" />
      </authorization>
    </system.web>
  </location>

I've also followed instructions mentioned in below URLs but still ​the error occurs.

 ​​ 

Please find attached screenshot. You can see that upload progress reaches to 100% and then throwing 404 error for handler.

Is this issue is related to form authentication?

Please guide./

Thanks,

Vinay

Hi Hristo Valyavicharski,

The above issue is resolved. I ​just put below tags to support in IIS 7.5 and it worked.

<system.webServer>

<security>
      <requestFiltering allowDoubleEscaping="true">
        <requestLimits maxAllowedContentLength="2147483647" />
      </requestFiltering>
    </security>
    <handlers>
      <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource" name="Telerik_Web_UI_WebResource_axd" />
      <add verb="*" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.Upload.RadUploadProgressHandler,Telerik.Web.UI" name="Telerik_RadUploadProgressHandler_ashx" />
    </handlers>​

</system.webServer>

But now I'm facing another issue. When ​i browse files with different name it works fine but when I browse file with the same name again. I'm getting below error.

TypeError: o.abort is not a function

if(o.currentUploadIndex==n){o.abort();     ScriptResource...a934158 (line 453, col 28)​

As I mentioned above, I'm using forms authentication and the page where I'm using RadAsynUpload is not authenticated(Anonymous access).

Please see the attached file for reference.

Thanks,

Vinay
