Quick Cache should not cache 404 Error pages

Plugin wordpress Quick Cache should not cache 404 error page or at least should send (404 not found) header when serving those cached pages so they will not be indexed in google search

with respect me … I had to do this to resolve the problem:

in (advanced-cache.php) before this line:

exit($cache); /* Exit with cache contents. */

add this:

if(strpos($cache,’Error 404′) !== false)
header(‘HTTP/1.1 404 Not Found’);

this is immature solution I know .. I wish the developer will fix this problem.

thanks
