Sometimes the requested page / resource moved to another location, then you have to route such a request to the new URL. This is the redirection.

Sometimes you need to use web application to implement password protected file downloading. This is useful for internal or commercial web application system.

WebRainbow provides the dedicated functions for the redirection and file downloading:

• Redirect
• SendFile

These two functions make redirection and file downloading easy.

The following demo, SendFile, will show the usage of these two functions for redirection and file downloading. It includes two small web applications, UrlRedirect shows how to use Redirect for redirection and FileSend shows how to use SendFile for file downloading, as well as 2 small web applications, Frame and FramePage, to glue them all together and hide all HTML file to make them more secured.

Click on following links to see the source code.

1. frame.html
2. logo.html
3. menu.html
4. main.html
5. Frame.bas (source code of "Frame" for Visual Basic 5 & 6, and Visual Basic 4 - 32bit)
6. FramePage.bas (source code of "FramePage" for Visual Basic 5 & 6)
7. FramePage4.bas (source code of "FramePage" for Visual Basic 4 - 32bit)
8. UrlRedirect.bas (source code of "UrlRedirect" for Visual Basic 5 & 6)
9. UrlRedirect4.bas (source code of "UrlRedirect" for Visual Basic 4 - 32bit)
10. FileSend.bas (source code of "FileSend" for Visual Basic 5 & 6)
11. FileSend4.bas (source code of "FileSend" for Visual Basic 4 - 32bit)
