Probably not - it depends on how you redirect.
In PHP:
header("Location: http://www.example.com/"); /* Redirect browser, emits 302 */
If you want to fix 301, use:
header("Location: http://www.example.com/", true, 301);
See the PHP documentation for more details .
If you do this in your own .htaccess:
Redirect 302 /PATH_TO_REDIRECT http://www.example.com/
then it will also emit 302.
Again, to emit 301, it's simple:
Redirect 301 /PATH_TO_REDIRECT http://www.example.com/
