How to Redirect Uppercase URLs to Lowercase

If you only have a few pages with capitalized URLs, you can simply set up some easy 301 redirects. If you have a ton of pages that need to be redirected though, you’ll probably find it much easier to implement a site-wide fix.

Option 1: Enforcing Lowercase URIs with Rewriting

The preferred method is to use server config files in your HTML code. If you have access to your httpd.conf file, try this method. It’s clean and works well. If you don’t have access to your httpd.conf files, your hosting company might be willing to turn the feature on for you.

Option 2: htaccess Redirect to Lowercase

An alternative method is using the htaccess file. Depending on the Apache version your server is running and any other rules already running in your htaccess file, this method can be buggy. On some servers, this can break images or cause the site to suffer from decreased speed. We’ve even received several comments from people who have tried the htaccess method and have caused their entire site to show a 500 status error. We’ve tested it on a few small sites and we didn’t have any issues, but you need to be very careful with this method.

If you want to try it, AskApache.com compiled this set of htaccess rules. Make sure your site is working properly after implementing this code before walking away from your computer!

I suggest setting up redirects for all of your sites, whether you have a URL problem or not, just as a handy catchall to prevent problems in the future. Preventing a problem now is much easier than trying to fix it later!
