To prevent EPiServer's Url rewrite to occur do the following to your element:
1) Add an id-attribute to your element
2) Add a special EPiServer attribute to prevent the rewrite
<link rel="canonical" href="the/url/not/to/rewrite" />
<link rel="canonical" id="canonical1" <%=EPiServer.Web.UrlRewriteProvider.UrlPreventRewriteAttribute %>="true" href="the/url/not/to/rewrite" />
