load different URL

[eluser]Unknown[/eluser]
Hi everyone, just getting started with CI and really liking it so far.

I have a really n00b question:

I've made a custom error handler so I can call an action before a 404 page is shown.

the action at the moment looks something like this.

Code:

function error_404()
{
        echo "<h1>404</h1>";
        
}

would it be possible to call a page based on a url in this function such as

/page/view/1231

without actually doing a redirect to /page/view/1231 ?

so that when the 404 error action is called, it actually shows /page/view/1231
