Caching and headers

Code:

HTTP/1.x 404 Not Found
Date: Tue, 22 Jul 2008 22:06:17 GMT
Server: Apache/2.0.52 (Red Hat)
Content-Length: 359
Keep-Alive: timeout=2, max=148
Connection: Keep-Alive
Content-Type: text/html; charset=iso-8859-1

Nope. I want to cache THIS:

Code:

$this->output->set_header("HTTP/1.0 404 Not Found");

i.e., whatever output the programmer has specified. Of course I don't want to cache every header; tons of them are automated and nothing to do with the programmer. But if the programmer has specified that he wants the header "HTTP/1.0 404 Not Found", I want that cached, so that his specified header is there next time too.
