Hi<BR><BR>What exactly is virtual directory?I know how u can create one and how it s used but could someone give me a more precise definition of what virtual directory is?<BR> Book im learning from claims each asp.net app has to have single virtual root directory but if i create aspx file in some physical directory(X) this web app will work anyway,even if i don t make X directory a virtual one.What am I missing here?<BR><BR>Thank you very much for helping<BR>bye
