How to remove double trail slash in CodeIgniter?

Question

CodeIgniter

I noticed that on my site which is on CI there is such a problem:
there is a foo controller, the
site.ru/foo/bar.html link leads
to it, but you can also access it through
site.ru // foo/bar.html
how to make the second the address gave 404?

Answer 1

1. There is an opinion that in canonical it is better to write an absolute link along with the domain
2. We made a rather "stupid" solution in each controller:

$app->vars->seo->canonical = ... ; //определяем ссылку

...

if (isset($app->vars->seo->canonical) && ($_SERVER['REQUEST_URI'] != $app->vars->seo->canonical) )
{
  header('HTTP/1.1 301 Moved Permanently');
  header('Location: '.$app->vars->seo->canonical);
  die();
}

This is probably not very beautiful, but taking into account the fact that the SEOs send their Wishlist regularly, I don’t see the point in fencing something more unified.

Answer 2

You don’t need to worry about it at all, just indicate the path of the page in the canonical meta tags, and everything will be fine with you.
