Redirect internal link to external site

not sure if i understand correctly (i guess i don't). if not, would you mind posting some example please? anyway, this is just a http redirection example based on uri.

e.g.

root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 172.28.20.111:443
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        clientssl {
            context clientside
        }
        http { }
        tcp { }
    }
    rules {
        myrule
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 22
}
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm pool foo
ltm pool foo {
    members {
        200.200.200.101:80 {
            address 200.200.200.101
        }
    }
}
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm rule myrule
ltm rule myrule {
    when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/ms365" } {
    HTTP::redirect "https://login.microsoftonline.com/"
  }
}
}
