Download, with java, a large file throughtout a size limiting firewall.

Well, I suppose that the title explains it quite well. But I think I'd rather explain the problem: I'm at work, and sometimes i need to download a file which is larger than the 26 mg limit firewall.

I am quite aware on how to download a file, using java or c#.

What i need to do is separating the file in smaller chunks, which is fine, but how would be done?

Do I need to, have to or can, "开发者_如何学编程masquerade" the file size, so it can be firewall approvable?

Any suggestions would be very much appreciated.

thank

As sanjay had asked me, the access is made through a webserver.
