Hey guys, I'm a bit confused. Here's what I did for one of my sites (a joke site): old url format: http://www.mysite.com/jokes/30.php new url format after using mod rewrite rules in .htaccess: http://www.mysite.com/jokes/30-The_Lawyer_and_the_engineer_joke.php Now this works fine for all my joke pages. I'm pulling the joke title out of the database and adding it to the jokeid. The question I have is do I need to somehow do a 301 redirect for all requests coming in from: http://www.mysite.com/jokes/30.php and send them to: http://www.mysite.com/jokes/30-The_Lawyer_and_the_engineer_joke.php I'm concerned that I will be penalized for duplicate content. Is that true? If I do have to use a 301 redirect, can someone tell me how I can do this using the example urls I've mentioned above? I've tried a few things on one page but haven't had any success. I guess I can make one entry per url in the .htaccess file? Any help would be greatly appreciated. Thanks.
