- bdfh42 18y agoPerhaps PG gets a pass
- brlewis 18y agoIt isn't at all unusual for dups to get upvotes, whether they're pg essays or not.
- tjr 18y agoI'm surprised that the same URL minus "www." doesn't automatically count as a duplicate.
- pmjordan 18y agoBecause unless the HTTP response is a redirect to the www. url (or vice versa) it's technically a document available at a distinct URL. For most servers, the two hostnames point to the same server (and vhost) but it's conceivable that they might not. You've got a similar problem with arbitrary appended query strings. I guess the clean way to handle this would be to detect very similar URLs and ask the user if it's the same document.
- prakash 18y agoTechnically, you can have one site on www.website.com and another on http://website.com http://website.com and hence they can be considered different and unique.
- tjr 18y agoCertainly, though it seems rare in practice. I suppose the possibility, however small, is enough to warrant not automatically assuming anything.
