Asp.Net wcf vs ftp vs httphandler for file upload

In my application i have to upload large files. Its a silverlight application which uploads the file using internet to some server. The application is installed on client machine. I was searching out for options that i can have. Any suggestion on which one would be better between WCF, FTP, Httphandler and why. I am using .Net 4.0 and save the开发者_Python百科 file to Sql using SqlFileStream.

The question really is: what problem are you trying to solve?

WCF is out of question since even if you get the browser to talk to a WCF service, it would have to be sitting on the top ASP.NET and doing what a simple ASP.NET page can.

Browser cannot upload FTP so that is out of question as well.

HttpHandler is an option but does not provide a benefit for uploads so you could use it but you might as well use a simple ASP.NET page.

Your main problems (and their solutions) are:

• ASP.NET is configured to accept up to 4 MB so you have to change configuration to allow more.
• To get a reliable upload, you need to implement a chunked uploading at client side using Silverlight or Flash but you do not seem to be going that route.

Update

Based on your updates, I would recommend chunked uploading using SilverLight on Client and HttpHandler on the server.
