Could you elaborate?.....
From what I can tell from your post (which isn't clear on the matter).. you have a webpage on your webhost that outputs a string of comma seperated data.
And you want to read this on your PC?.. (perhaps use a browser?..)
From your post, I can't make out what the topic title has to do with it. I don't see anything relating to arduino, serial communication or what you intend to do.
You'll have to provide more info and more context for us to provide any sort of assistance.
