We have a commerce site that has been totally screwed by googe recently... i know, welcome to the club.
It shows only the home page (www.domain.com), index/php and some 900 plus shopping cart related pages with caches from mid last year (over a thousand product, content and article pages have simply vanished)... sound familiar?
My question though is to do with the www.domain.com and www.domain.com/index.php.
Google is seeing them as two distinctly different pages, with different cache dates (may 26th and may 30) and different pr (4 and 3 respectively).
My server admin says you cannot do a 301 redirect of the /index.php to the www.domain.com without creating an endless loop.
So my question is what to do about the duplicate content issue and the splitting of the PR... ?
Any suggestions or input please... or even a link to a previous thread discussing this issue (i took a quick look and couldn't find anything current enough)...
