Case insensitive routing in laravel

filters.php

App::before(function($request)
{
	// if any characters in the route path are uppercase
	if(ctype_upper(preg_replace('/[^\da-z]/i', '', $request->path()))){
		// extract the path section of the url (the route) from the url and convert it to lowercase
		$sNewRelativePath = str_replace($request->path(), strtolower($request->path()), $request->fullUrl());
		// now redirect the user with a 301 to the lower case route
		return \Illuminate\Support\Facades\Redirect::to($sNewRelativePath, 301);
	}
});

@alexandreetf open the app/filters.php file, you will find the App::before function there, then just insert the conde above in.

This was really helpful, however middleware is now preferred in Laravel 5. Here is a gist that I created with a middleware class that is similar to this filter.
