Description: Split a HTML (HyperText Markup Language) document's URL (Uniform Resource Locator) up in parts - but only URLs from a Hard Disk Drive. Used here to let the user redirect a page to a similar page placed on another drive letter - for example, change from a computer drive to a network drive. / Beskrivelse: Split et HTML (HyperText Markup Language) dokuments URL (Uniform Resource Locator) op i dele - men kun URL'er fra et harddisk drev. Bruges her til at lade brugeren omdirigere en side til en tilsvarende side placeret på et andet drev bogstav - for eksempel skift fra et computer drev til et netværksdrev.

//   The method charAt is used to extract a single character from a

//   The method substring is used to extract a range of characters 
//     from a string from start position up to but not including end 
//     position.
//   The method indexOf is used to search for character with a string - 
//     searches from the beginning (left side) of the string. Optional 
//     second argument that specifies an initial index at which to start 
//     the search.
//   The method lastIndexOf is used to search for character with a

//   Character positions are zero based, so that all indices must fall
