 We run a site which is reachable by multiple subdomains (nb. not
 multisite) For example customer1.site.nl, customer2.site.nl. A plugin uses
 the subdomain to display different data for each customer. The site url is
 set to www.site.nl.

 Since a recent update this stopped working. The visitor is always redirect
 to the site url www.site.nl.

 I tracked down the problem to canonical.php. When I replace this file with
 the version from 4.4.2 the old behaviour is back, ie. the subdomains are
 not redirected.

 There are no rewrite rules for these sub domains.
