    I have a web application in which I am currently using Microsoft's standard upload control.  However, users are having problems with uploads not completing when they try it from locations with poor connectivity.


    1. Could your upload control improve the situation?

    2. Can your upload be restarted, i.e., if a timeout occurs does it save what was already received so that it can pick up from where it left off?

    3. Are there IIS changes that you recommend to better handle upload processing?

    Thank you

    Hello Rich,

    We have already answered to this question in the support thread opened. For a community reference I will paste the answer here as well:

    I believe that the reason your users fail to upload is due to the web.config configuration, not because of the ASP.NET FileUpload. The ASP.NET FileUpload, as well as RadUpload, are based on the html <input type='file' /> element, which in turn has been used for file uploads since the advent of the web. The issue that your users face is a timeout issue I believe. If they are uploading from a slow connection the server  might timeout the request. Hence, the upload will fail. In order to workaround that, please consider setting higher value to the executionTimeout element in the <httpRuntime /> section of the web.config.  For details, please take a look at the following blog post.
