As Kirk mentioned, the only transparent url support is with open-uri.  
Also File.exists? does not really make sense for a url. A given url  
does not necessarily point to a real file. Does it exist if you get a  
response code of 200? What about 302? What about 404? Sure the  
webserver says it doesn't exist, but you do get some content back  
usually.
