Problem with "Canonical" tag in Drupal 7?

Question

CMS

There are pages on the site with addresses in the form:
site.ru/novost-dnja
, you can go to
site.ru/novost-dnja.eofvqrfqlsht
site.ru/novost-dnja?eofvqrfqlsht
site.ru/novost-dnja&eofvqrfqlsht
and the same page. the problem is this, the engine generates canonical tags on these “subpages” of the form:

<link rel="canonical" href="site.ru/novost-dnja&eofvqrfqлщт" />

Instead of indicating that this garbage page is just a copy of the main one. So the canonical should look like this:

<link rel="canonical" href="site.ru/novost-dnja" />

Tell me how to implement it, please.
PS^ is used by Pathauto to create CNC addresses and Global Redirect to redirect pages /node/123 to pages like site.ru/novost-dnja

Answer 1

Install Metatag, it has a separate canonical through tokens. Checked on their sites, there is no such problem.

Answer 2

With it, you can confirm a third-party short link code.google.com/p/shortlink/wiki/Specification
And this can happen using a head request to your server, without having to load the entire page
