Bad URI with oauth token

Bad URI error occurs when we do OAuth verification. (I found it because of Facebook connect)

This is because the OAuth token contains a special character, precisely, |. I think there can be other characters that cause Bad URI error.

Moreover, I have found that the Bad URI only occurs with WEBRick, a webserver provided by Ruby.

Therefore, in order to fix it, I had to modify Ruby source code.

Here is what I have done:

In the file httpresponse.rb, which resides in C:/Ruby187/lib/ruby/1.8/webrick (This depends on where you installed Ruby)

Around the line 164:

      # Location is a single absoluteURI.
      if location = @header['location']
        if @request_uri
          @header['location'] = @request_uri.merge(location)
        end
      end

Add URI.encode() around location before @request_uri.merge()

# Location is a single absoluteURI.
      if location = @header['location']
        if @request_uri
          @header['location'] = @request_uri.merge(URI.encode(location))
        end
      end

And that's it.

I'm gonna fix this in the Ruby open source project also. This will be my first open source participation, yeahhhh.
