Rails - Apr 2007 - URL check URL validity

Hi everyone,

I have a web app that at some point asks for a URL ... and i need to
check that url''s validity ... is there a way to do that in RoR...
- in C# i would to something along the lines of

HttpWebRequest hReq (HttpWebRequest)WebRequest.Create(url................);

HttpWebResponse hRes = (HttpWebResponse)hReq.GetResponse();
rCode = hRes.get_StatusCode()...etc

Any input is greatly appreciated.


Thank you,

I would say a lot depends on what criteria you are using to qualify a
URL as valid.

require ''uri''

def valid_uri?
   begin
     myuri = URI.parse(some_string_that_might_be_a_URL)
   rescue URI::InvalidURIError
     return false
   end
   # other checks on myuri.host or myuri.scheme to enforce  
application rules
   # return false if myuri.scheme =~ /javascript/i
   # etc.
   return true
end

Something like that?
