Sending large data over the Internet

Hi,

First of all, I am not sure whether I have posted into the right forum or get the technology correct in the first place.
Hope someone can help clarify.
Currently I am writing a web application. This web page will receive data from a web user through a browser, and depending on the type of data, send that data to different machines for processing. (aka, each machine provide a different service)

However, a large amount of data needs to be sent over the Internet. We are talking about data as large as 55Gbyte.
The general question is whether we can stream that data from the web user to the web application that resides in the web server. Which the web server will then stream that data to the different machines.

How can this be done? Or is there a better alternative to deploy this than using a web service?

Sending that amount of data wouldn't be a problem, but of course depending on the size of your line and the quality of it will make a difference. Also, if this is going to be a regular occurance, I'd consider using an ftp site.

If you have Legacy systems and access to X25, then I'd think about using that since it's going to be more secure.
