URL Class

Set of class functions I use from time to time.

1. isValidURL - Returns TRUE/FALSE if the string is a Valid URL
2. stripWWW - Strips the WWW off the incoming URL
3. getDomainName - Strips the WWW off the incoming URL
4. Status_Code - Returns the Status Code of a URL ie(200 or 404)
5. FavIcon - Get an image object of the FavIcon, Returns (T/F) if present
6. Save_FavIcon - Saves the Websites FavIcon to the File/Path
7. GetParam - Returns a Form Value
8. isMobileDevice - Tests the User Agent to see if it is a mobile device
9. isSpiderBot - Tests the User Agent to see if it is a Bot/Spider/Crawler
