if you use multi_step_login as a class in entry point link i will look like as below
<entry method=”GET” dst=”http://mydomain.com/default.aspx?mykey={secretkey}”>
if you use multi_step_login as class this time verification script will execute each time
when the customer login into the customer control panel.and the “secretkey” is updating every time through verification script and that changes will affect in the entrypoint url through value of settings.
