Best way to set a pool member as Disable from Irule

based off this post https://devcentral.f5.com/questions/how-to-run-a-bash-script-in-irule-with-a-parameter-to-that-bash-script-

i have used a sideband connection with a PUT to icontrol to set the member as user-disabled. The only issue is that i have to use a data group to translate from member ip:port ( what i rules use) to member name (what i control).

Anyone know a better way then a data group to do this?

the magic line for the put looks like:

`set req   "PUT /mgmt/tm/ltm/pool/~[lindex $test end-1]~[lindex $test end]/members/~[lindex $test end-1]~$member:$port HTTP/1.1\r\nHost: localhost\r\nAuthorization: Basic BASE64GOESHERE\r\nContent-Type:application/json\r\nContent-Length: 27\r\n\r\n{\"session\":\"user-disabled\"}"`
