Yesterday I got upset that Yahoo Search Still Not Listening to 301 Redirects. Sometime yesterday afternoon, we were getting reports that this is now resolved.
An updated WebmasterWorld thread has the individual upset with how was handling those redirects in the past saying things are now looking better. Here is his post:
This seems to be clearing up on its own.I no longer see the non-canonical URL in the links of Yahoo search results; The link in the SERPs is now correct. However, I do still see a non-canonical home page listing in Yahoo Site Explorer when "Show pages from: Only this domain" is selected.
I am happy to see this resolved or being fixed.
