How do I upload large (> 25MB) files to a web service?

Question

I have a web service that takes a byte[] and saves it.

This works fine for \"small\" files, but once I hit a certain size the web service fails and returns \"The req

Answer 1

If I was stuck having to use web services and needed to support very large files I would look at implementing a system that allows you to upload files in pieces.

Eg.

• ticketId GetTicket(size)
• UploadData(ticketId, byte[] payload) (this can be called as many times as you want)
• FinalizeUpload(ticketId)

This would allow you to chunk up the big uploads, and not hold too much data in memory. The disadvantage is that you are still using a fairly inefficient transport mechanism.
