I installed WP Super Cache today, and I love how fast it makes my pages, but I've noticed that URLs ending in /index.php are no longer redirecting.
Funny thing is, they still redirect for my home page; aka http://www.mypage.com/index.php still redirects to http://www.mypage.com, but my individual post pages do not, aka: http://www.mypage.com/10/2009/todays_post/index.php
Even funnier thing -- I am now discovering that they DO redirect correctly on a Windows machine running IE and also Firefox, but not on a Mac running Firefox (strangely, they still work when i use Safari!)
Any ideas? Is this even a problem? I'm trying to avoid duplicate content here. If I turn off caching they work fine again.
Thanks in advance!
