Help regarding an iRule

the requirement says that we need the incomming requests to come on port 8080(http) and then redirect these to https.

the https is on port 443, isn't it? so, you will create new https virtual server, won't you?

e.g.

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:8080
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        http { }
        tcp { }
    }
    rules {
        _sys_https_redirect
    }
    source 0.0.0.0/0
    vs-index 7
}

[root@ve11a:Active:In Sync] ~  curl -I http://172.28.24.10:8080/something
HTTP/1.0 302 Found
Location: https://172.28.24.10/something
