> There are two styles of URL in circulation for URLs into Mahout's Wiki (presumably an Apache-wide configuration issue):
> https://cwiki.apache.org/MAHOUT/svd-singular-value-decomposition.html vs
> https://cwiki.apache.org/confluence/display/MAHOUT/SVD+-+Singular+Value+Decomposition
> They appear to be the self-same confluence 3.4.9 installation (or its raw filetree). Each has a different search box at the top of the page. The version with 'confluence/' in the path does a confluence search, and returns similar URLs as results. The one with '.html' suffixes does a domain-constrained Google search. 
> Despite markup canonicalising the confluence variant, ie.  <link rel="canonical" href="https://cwiki.apache.org/confluence/display/MAHOUT/SVD+-+Singular+Value+Decomposition"> appearing in the confluence pages, it seems the Google search results typically throw people into the other version of the Wiki site.
> This is all mildly confusing, mildly annoying but overall mostly harmless. It could be having some negative impact on google rank & suchlike, since incoming links will be split between the two styles. Maybe this could be passed along to the Wiki admins? 
> Which version does the Mahout team consider canonical URLs (for external links etc)?
