Simple Reverse/Proxy Redirect?

We have a pair of F5 LTM 8400's 9.x and would like to use it to replace a couple Apache Reverse Proxies. We have an external HTTPS/443 VIP that we would like to securely redirect/proxy all HTTPS connections to a transparent internal HTTP/80 VIP to our corresponding .NET app servers. We would still like all connections to go thru the external VIP. What would be the best way to accomplish this?
