W3C.pm line 223 does not view a redirect as a success

[TomasDawe]

The default URL for string validation is currently under a 302 rule.
According to LWP this is not a is_success.
it might be wise to change 223 to
if(index($response->{_content},"Status: 30") > -1 || $response->is_success)
as this will take into account redirects.

I am hesitant to hard code the 302 URL as this will likely be removed at some point.
Opinion?
