    Upload not working

    The UploadPersistedFile control works locally, both via the built-in Dev Server in asp.net, as well as locally on the server itself.  But it doesn't work from my browser to the remote server.  It starts to upload the file, then prompts for credentials when it gets to the end.  If I re-enter my credentials, it prompts again.  If I cancel the credentials prompt, I get a javascript alert: "Error, HTTP, 401".  Nothing is in the UploaderTemp folder (which I manually created). 
     
    The local Network Service has Modify permissions to the UploaderTemp folder (and if I remove these permissions, it stops working locally as well, so it would appear I have the permissions straight). 

    What would cause this?  
     
    FYI, we are still in the process of purchasing the product (things move at a glacial pace here).  Could that cause this pattern?  There are no license-related error messages generated.
     
    Thanks,
    Brad

    Brad,
     
    Is your remote server using WINDOWS AUTHORIZATION? Does the IIS disable the ANONYMOUS AUTHORIZATION?

    Re: Upload not working

    It is using windows auth, and allow anonymous is unchecked.

    Re: Upload not working

    It is IIS6, it is running in an app pool that uses the Network Service identity.  I granted Modify permissions to the UploaderTemp folder for Network Service.

    Re: Upload not working

    Hi,
     
    Currently Flash-plugin is not support your case.
     
    If the browsers installed Flash, the Uploader would try to use Flash to upload,
     
    And then the Flash would prompt the username/password.
     
    We already provide a method to just disabled the Flash mode :
     
     
    That should let your application work on your server.
     
    Without Flash plugin , the Uploader would choose Silverlight/IFrame mode.
     
    If the browsers do not install the Silverlight ,
     
    The Uploader would not support multiple files selection.
     
    So we suggest your end-users install Silverlight to get better experience.
     
     
     
    We also found that Flash10 can support you case , (not make sure..)
    Maybe you can also test the Flash10.
     
     
    Regards,
    Terry

    Re: Upload not working

    Bear in mind that from the same browser, it works if the web server is local, but does not if the web server is remote.  How could Flash be playing a role in this case?

    Re: Upload not working

    OK, I tried adding UploadType="IFrame" to the HTML.  Same result: it works locally, but not remotely.  Here is my HTML control declaration:
     
    <CuteWebUI:UploadPersistedFile UploadType="IFrame" runat="server" ID="uplFile" InsertText="Browse" ManualStartUpload="false" MultipleFilesUpload="false" OnFileUploaded="uplFile_FileUploaded" TempDirectory="~/UploaderTemp" ></CuteWebUI:UploadPersistedFile>                                            
     
    Again, environment is as follows:
     
    • IIS 6.0
    • Windows Server 2003
    • Enable anonymous access = unchecked
    • Integrated Windows authentication = checked
    • Framework 3.5 is installed, and the app is targeting v3.5
    • Web Site app pool identity has Modify permissions to UploaderTemp folder
    Works locally, does not work remotely.  Please help.

    Re: Upload not working

    Any progress on this?  If I take your sample and upload it to our server, disable anonymous access, and use integrated windows authentication, I get the same result.  It only works when Allow Anonymous is checked.  FYI, the identity used with Allow Anonymous is (currently) an Administrator, also the identity used by the App Pool is an administrator.
     
    This is pretty critical for us.

    Re: Upload not working

    so it seems this just doesn't work with intranet sites (e.g., integrated windows authentication) hosted on W2K3
     
    the iframe mode ends up loading the file into server memory, which won't work for very large files
     
    if you can figure out another solution, let us know

    Re: Upload not working

     
    Currently I still do not know what's wrong.
    Because the IFrame/Silverlight modes are OK when we tested it.
     
    I suggest you install Silverlight and test the Silverlight and then reply me the result.
     
    Thanks.

    Re: Upload not working

    It does work with the IFrame mode, but the file gets loaded into server memory.  This is not viable for very large files.

    Re: Upload not working

    Hi,
     
    If your website using ASP.NET1.1+Medium trust level , the uploader would not able to intercept the raw request data into the file stream.
     
    So I suggest you 3 solutions:
     
    1. upgrade to ASP.NET2.0
    2. use Full trust level
    3. let end users use Silverlight.
     
    Regards,
    Terry
  •  01-12-2009, 1:42 PM 47663 in reply to 47476

    Re: Upload not working

    1.  It is ASP.NET 3.5
    2.  It is Full trust
    3.  Silverlight works, but end users require admin privs to install, which is not an option for us.
     
    Any other ideas, or are we at a dead-end?
