I just thought what is the shortest URL in the world which works :

http://www.com/

http://users.aol.com/rynocub/this.is.a.very.long.url/this.very.long.url.was.created.by/the.rynocub.home.page/which.was.created.by/ben.tolsky/and.radioactive.chicken/which.is.a.ben.tolsky.company/this.url.is.the.longest.url.made.by/ben.tolsky/finally.this.is.over.htm
