text: how to get past url hiding schemes by understanding how domino uids or other numbers are created? i'm trying to create a lyrics application that will download lyrics from various web-sites, but there is only one web-site that has not hidden the lyrics they have under different schemes.   the one web-site which has a clear url scheme is www.lyricsdirectory.com which goes something like this  a standard format for lyricsdirectory: http://www.lyricsdirectory.com/index/firstletter/bandname/bandname - songname lyrics.htm firstletter being the first letter of the band's name, bandname being the band's name, and songname being the song's name.   others, like sing365.com utilize domino unique id hexadecimal numbers in their lyrics urls.  for instance the link to bush - macinehead would have a 32-bit uid after it:  http://www.sing365.com/music/lyric.nsf/machinehead-lyrics-bush/0000000000000000000000000000000  all i want to do is create a third party application, crediting the web-sites that give the lyrics, which brings it all together but most of these web-sites use url hiding. i think you might find this article on wikipedia interesting:  http://en.wikipedia.org/wiki/uuid
