<BODY>
This example demonstrates how to upload a zip archive and extract it on a
server.<br>
.NET Zip component <b>SharpZibLib</b> is used for extracting file on a server.
More about SharpZipLib library you can find on the official site:
http://www.icsharpcode.net/OpenSource/SharpZipLib/
<br>
<br>
Extracted files will be stored to the "UploadedFiles" folder that is located in
the root directory of an examples.<br>
You should grant write access to "UploadedFiles" folder to the ASP.NET process
identity(typically {MACHINE}\ASPNET on IIS 5<BR>
or Network Service on IIS 6).
