1. What you have done above is not a redirect. You want HTTP::redirect {http://www.site.com/page1}
2. If however you are just trying to pass traffic unencrypted to a back end server then you don't need to do this at all. Just set the pool to be the http servers and make sure server ssl is set to none in the VIP configuration.
3. Use a HTTP class for this, its designed for the job. Note that a VIP must still be configured to answer on port 443 to handle the incoming HTTPS requests
