Can you provide any additional information? The summary is ambiguous.

Specifically: what website is this for (URL) and what do you want the user to see?

mozilla.com/aurora and firefox.com/aurora currently doesn't exist. the request is to redirect these links to http://www.mozilla.com/firefox/channel/ page. anyone who types mozilla.com/aurora or firefox.com/aurora, we can direct them channel page where they can find a bit more info about the aurora channel and download it. thanks

This is in place for www.firefox.com/aurora -> www.mozilla.com/firefox/channel. Redirects on www.mozilla.com are handled in an .htaccess file that webdev manages. Kicking this over to them. Webdevs, something like this should do the trick (in the main .htaccess file, somewhere in the section that starts at line 250): Redirect permanent /aurora https://www.mozilla.com/firefox/channel/
