CodeIgniter turn off automatic routing?

Question

Is it possible to turn off the automatic routing in CodeIgniter and have it only process requests if a route for that request exists? Thanks.

Accepted Answer

Keep in mind that Dale's solution:

```
$route['(:any)'] = "some/default/controller/$1";
```

only works for one-segment URLs, like:

```
example.com/foo
```

but not for:

```
example.com/foo/bar
```

You can get around this by using a regular expression instead of the CI wildcard. And by routing to a non-existing class drops a show_404() indeed:

```
$route['(.*)'] = "none";
```
