URLDecode function

Areas>Languages>VBScript
Areas>ASP / ASP.Net>Functions>Conversion

When a browser sends form data to the server, it uses one of two encodings method:

1. application/x-www-form-urlencoded. This encoding is default. Next VBS code is function, which lets you decode such data (reverse function for Server.URLEncode).

2. multipart/form-data - You can use Pure ASP file upload with progress to decode such forms.
