I've been working on Windows Forms and database management with VB.net,ADO.net for quite some time now,but I think its time for me to study web services and web pages using asp.net.Now I'll be buying IIS in a few days.
But what I wanna know is what exactly is the difference between a server and a proxy server.What can a server do that a proxy server can't?Also,can servers be used in free domains such as web pages in Geocities or Angelfire?
