How do I make routes case insensitive?

I don't know that you'd necessarily want routes to be accessible at both /user/... and /User/... might take a hit against SEO that way.

You'd probably be better off using some middleware to rewrite paths to lowercase then redirect with a 301 if the initial request wasn't all lowercase.

Why would you have links with improperly cased paths to begin with though?

@willvincent, I thought it was common that sites respond to a route ignoring the lower or upper case. But seems like it's not true, right?

Guess it depends on the site.

@Mithridates I don't think it's common at all. For example, http://google.com/analytics works, but http://google.com/ANALYTICS doesn't. http://facebook.com/messages works. http://facebook.com/MESSAGES doesn't.

Depending on your hosting, and if you are using apache, you may be able to do something;

This might cause problems elsewhere but you can strToLower in your index.php file

I have added the GLOBALS line. Now it does not matter about the case, but by the same token, its not possible to use case to differentiate routes or pass mixed case parameters;

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$GLOBALS['_SERVER']['REQUEST_URI'] = strtolower($GLOBALS['_SERVER']['REQUEST_URI']);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

Thanks all, It comes out that this is not a common pattern at all, so I ignore it as well!

@Mithridates I implemented this when a user wanted a short link to redirect users to their event page. The URL was printed on posters with a capital letter at the beginning and people were typing it in lowercase, this solved the issue.

Route::get('/foo/{bar}', function ($bar) {
    switch (strtolower($bar)) {
        case 'baz':
            return Redirect::to('/foo/baz')
        default:
            break;
    }
});
