DNS Redirection iRule

Greetings,

I got a rather peculiar request, where the internal security department is getting warnings regarding some websites that are being requested and used with their trailing dot DNS name (e.g. : "www.google.com." ).

I'm not really sure on the reason why this is being requested (waiting for an answer), however I'm looking on ideas on how to implement this swiftly. I was thinking of using a DNS iRule so that if that name is being requested, it sends a redirect to the counterpart without the trailing dot. However the iRule would need to fetch the WideIP name and therefore apply the redirect.

Do you guys have any ideas on how to implement this?

Thanks a lot for any inputs you might have.
