Rel Canonical Alt Host – sets the canonical link to another server. Very useful plugin for SEO, as it prevents the duplication of content and, therefore, penalties from search engines. Make sure you edited the configuration and set the value of the alternative host before enabling the extension.
For example, if the canonical url was primer.ttt/blah and you set the host for the image alt = bar.ttt, then a new tag will bar.ttt/blah. You also have the option to use queries in the search.
