Try to set r->err_headers_out.

For content-type you could check the configuration directive DefaultType.

You could also set Cache-Control with the Headers directive. Check its 
"always" option too.

You can also combine the Headers directive with environment variables 
set in r->subprocess_env. Check 
http://httpd.apache.org/docs/2.0/mod/mod_headers.html#header
