This is probably a really stupid question, but I am in the midst of redesigning my site and am renaming from shtml to php3, the search engines have my pages as shtml (actually they still have some html) how do I keep visitors from hitting the 404 page everytime they click on a link from the search engine? I have ALOT of pages, making a META redirect for each page seems a daunting task, is there an easier way?
