http set cookie and a http reply redirect via policy

The default strategy is first-match, so only the first rule is triggered. Change that to all-match, and should work.

Example from my lab, where I successfully tested this:

[root@LABBIGIP2:ModuleNotLicensed:Active:Changes Pending] config  tmsh list ltm policy policy1
ltm policy policy1 {
    controls { forwarding }
    requires { http }
    rules {
        cookie {
            actions {
                0 {
                    http-set-cookie
                    response
                    insert
                    name stop_mobile
                    path /
                    value yes
                }
            }
            ordinal 1
        }
        redirect {
            actions {
                0 {
                    http-reply
                    redirect
                    location http://asm.lab.local/
                }
            }
            ordinal 2
        }
    }
    strategy all-match
}
