Hi Luigi,

The reason why I'm thinking I should try to redirect those 4 links in my example (and any that would duplicate the url of my home page) is because of Google. Ranking in Google is very important to our site, and so far, Google is seeing these links as being duplicate pages of our home page! First, I did figure out how to block these urls in robots.txt, so that is already done. The common pattern I saw was "/?" and I blocked it (without affecting any other important urls) like this:

Disallow: /?*

I don't know why Google would even find or list these urls, but it keeps coming up with more "duplicate pages" like this that don't actually exist. Also, I have to be careful about using canonical methods for the site because that prevents some of the applications I need (like Jevents) from working right (for example, adding events from the front end depends on a redirect to "home.php"). I have only been learning about these issues as I go along, and when I look in Google Webmaster tools, I see they are reporting "duplicate" title tags, and meta descriptions and continually coming up with new ones. Even though they claim Google can tell which page is the main one, they also penalize if a site has duplicate content, and will continue to do so, according to the latest reports.

Thanks for your help!

Thank you, Luigi, I appreciate all your help.
