I have a few questions about the meta refresh tag.
First of all, does Google view it as a 301 or 302 redirect if the delay is 0 seconds? I've read various sources and they seem to vary. Also, does any PR decay take place through this "redirect"? I mean, it obviously does, but I'm guessing the amount varies depending if the search engine views it as a 301 or 302 redirect.
Finally, is it possible to use the meta refresh tag, not to redirect to a new domain, but rather to fix duplicate content issues (e.g. by redirecting from a non-www domain to its www version)?
I am aware that 301 redirects are preferred, so please don't bother trying to educate me on that.
I am just wondering as my web hosting company does not allow or support 301 redirects, and I'm wondering if this is a possible way to fix duplicate content issues without a 301 redirect.
