We will see some of the code samples to upload files to a SharePoint or a mapped drive using HTTP PUT methods.
ASP.NET UI code is going to look something like
UI code
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="FileUpload1" runat="server" Width = "500px" />
<br />
<br />
<asp:Button ID="UploadButton" runat="server" OnClick="Button1_Click"
Text="Upload File" />
<br />
<br />
<asp:Label ID="Label1" runat="server">asp:Label>
div>
form>Upload Code
