Urgent: Help setting up a 302 redirect while preserving the original URL/Address

I want to setup the below 302 redirect and keep the original URL/address in the browser. I know we can do this on Apache but is there a way to implement it on the F5?

www.abc.com/xyz --> www.def.com

The user types in www.abc.com/xyz and redirects to www.def.com but in the browser the original address www.abc.com/xyz is displayed and the user never knows the destination/redirect url.

Thanks in advance.
