sc_trans relay and remote app question

[trahma]

I realize sc_trans is out of support, was hoping someone here may have some experience with my use case.

My station uses the remote application playlist control that calls a script I've written to retrieve the next song to play. I would ideally like to have the option to tell it to relay a url but returning a URL instead of a filename seems to not work for me.

I'm attempting to achieve allowing DJs to connect to an sc_serv instance so they can test their connection, and then have sc_trans relay that connection to live.

Anyone have any suggestions for how to achieve this with sc_trans?
