I’d like to redirect urls in a WordPress site and I could use recommendations for good plugins or methods of doing this effectively and cleanly. What I’d like to do is redirect something like:

http://acmesite.com/pathA/page.html

to:

http://acmesite.com/pathB/page.html

What I want to do is change a top level menu item on the site without breaking all the links to the underlying pages. I can change the links I am aware of but I’d like to ensure that legacy links still resolve to the correct page on the new URL path.

Any suggestions how best to do this?
