Help needed invoking multiple addresses

[sebastienros]

I'd like to create a LUA script which would invoke different addresses (not paths) each assigned to a thread. It would be similar to the addr.lua script that is provided as a sample, but using specific addresses instead of doing using the lookup method. The goal is to spread the load on different ports of the same server.

I am thinking that these addresses could come from the script arguments, or from a port range taken out of the main addr argument. My issue is that these come as strings, and the thread requires and addr type. I don't understand how to do that with the LUA extensibility. I found a parse_url method in the source but it's not available to the LUA host AFAIK.
