911003 - downloading via nusoap
 

hi
a client application is written in C# by Visual Studio which calls some web services in an Ubuntu server which are implemented in php and get available via NuSoap. a web service is required to download a file from server to client. the file may be as large as 1GB.
what's your suggestion for downloading the file into the client in such a condition? what aspects must be payed attention to and totally what's the best method for this purpose?
thx
