I'm still not very clear what's the "correlation" you mean here. The correlation means that the server generates some dynamic value and send to the client, and later the client must use the dynamic value that generated by the server as a token sending back to the server. The correlation value must be "Server Generated".
From your description, do you mean the parameterization? Do you want to change those values, for instance, change the value by iteration? If so, you just need to create your own parameters for those numbers.
So if you really mean the correlation, the dynamic value generated by the server, you can use web-http/html to do the correlation. If you using the TruClient protocol, no correlation needed.
If you mean "parameterization", both web-http/html and TruClient will do the job. You can use the shortcut Ctr+L to open the parameter list window to add parameters.
