This Umbraco extension automatically creates canonical meta tags, if
the url used is not the one found by Umbracos NiceUrl. Especially
useful if you use umbracoUrlAlias or umbracoUseDirectoryUrls
use the extension, download the package and install it to your Umbraco
solution. When done, just add the [DI]Canonical macro to your
templates. If you have a page, that uses that template and uses
umbracoUrlAlias and the user/serch enginge came via that link, the
canonical meta tag will be present in the header.
NOTE: Your head tag must have runat="server"
