Hello, Telerik Team

We are currently using the RadUpload for handling file uploads in our clustered environment running IIS6. But we are experiencing some problems. When for example a user wants to upload a large file and the user has a limited upload speed an time-out occurs. We could increase the executionTimeout but thats not an option for us.

So we took a look at the Silverlight upload control, but we still have some questions:
  • Can we use the control in our clustered environment running IIS6?
  • Do we still have to increase the executionTimeout?

Thanks in advance,
Jeroen Speldekamp

Hello Jeroen,

Thank you for your interest in the RadUpload for Silverlight.

Generally you can use the RadUpload in a clustered environment but you should be aware of the following:
  • If you have one centralized Upload Location (a database or a shared folder on one of your servers or another load balancer for you file operations) then you should use one of following techniques:
    • The TargetPhysicalFolder property of the upload control and a standard upload handler.
    • Custom upload handler. The code inside the handler should be aware of the centralized upload location.
  • If you spread the upload folder on all servers then you should tune-up the load balancer to return the same backend server for all requests from one PC/IP. This way all chunks (from the uploaded file) will be saved in one place/file. Of course you should synchronize the content of all upload locations after all.

About the timeout.
Each file is uploading by chunks. By default the chunk size is 100'000 bytes but you can change it via BufferSize property. Regarding this mechanism there should not be a delay or timeout when you are uploading large files.

We hope this information will help you.

All the best,
Ivan

Hello Ivan,

Your information was very helpful, thanks. I'm going to download the trial version and see if I can get it to work on our environment.

All the best,

is there any examples of using a network path to save the files? I can't seem to get this to work.

Thanks,
Ryan

Hello Ryan Riebeling,

You can specify the relative path to the virtual folder of the web app and also you can change it in the silverlight app. Is this what you want? There is an KB about similar scenario. Read more.
If this is not your case, can you send us example project and more details on what you want to achieve.
Thank you.

All the best,
