Thanks for your helpful reply, wige. But perhaps I should backpedal here and ask if I the redirect is even all that helpful for Google, and, considering all the unanticipated extra work it creates, whether I should just leave my site alone.

Without the redirect, I have one set of links, and my only problem is redundant home page links between mysite.com and mysite.com/index.php.

With the redirect, I have to not just remove all index.php references in the database of my blog, but locate and remove many more in the blog structure files. I'm not sure if this is advisable.

Any further thoughts regarding the value of the redirect?

Thanks.
