I am doing a redevelopment of our company's website, and in the process changed some file names and a lot of the .html files became .php. Sorry if this question is asked on a frequent basis, but I was interested in setting up my .htaccess file to redirect anyone going to a .html page to automatically go to a .php page (although there will be certain file name changes I'll have to specify, not sure how that will work). Since we rank, this is essential. Thanks!
