Something is remapping my pages. I used tio have a page called example.com/prefix/ABC/topic and a page called example.com/prefix/XYZ/topic. I deleted example.com/prefix/ABC and everything under it, so example.com/prefix/ABC/topic should now be returning 404. But when I access example.com/prefix/ABC/topic by entering it into the address bar of my browser (Firefox 3.6) I do not get a 404. Instead I get example.com/prefix/XYZ/topic.
It appears that some excessively helpful service is noticing the 404, finding an alternate URL with the same leaf name (in this case "topic") and redirecting to the "corrected" URL.
I am pretty sure that the issue is not a browser issue because Google denies requests to remove the example.com/prefix/ABC/topic URL from their cache because it does not generate a 404 when the GoogleBot tries to access it. And when I send the GoogleBot directly at the target URL example.com/prefix/ABC/topic it happily reports success at fetching prefix/XYZ/topic/. So I think the wordpress server is giving the extra help. I speculate that a hyperactive spelling corrector is the cause.
How can I tell it to stop helping?
The blog I need help with is tactilerevolution.wordpress.com.
