Best Practices for Uploading Large Files in ASP.NET: how to do it right?

What are the current recommended methods for uploading large files using ASP.NET Web Forms and/or MVC without encountering timeouts?

  • Adjust Server.ScriptTimeout for the specific POST request;
  • Consider utilizing client-side flash uploaders such as swfupload () or plupload (), though be aware of potential issues with proxies;
  • Explore a gmail-like JavaScript solution like http://code.google.com/p/gwtupload/

Answer №1

Almost every major component suite comes equipped with an upload control feature, making it easy for users to seamlessly upload files. If you are already using a component suite, consider utilizing the built-in upload tool provided.

It is important to ensure that any upload tool you choose has the capability to stream directly to IIS (Internet Information Services), rather than first uploading all data to memory before writing it. This will help optimize performance and efficiency when handling file uploads.
