Check out Ray's cfthread / cfjoin proof of concept, I bet this would do the trick perfect =)

I am working on a project. The cfm page in my project I call "TheBrain.cfm" this is the page that gets called by my task scheduler every 4 hours. TheBrain.cfm script then makes calls to a web service. I am allowed to have 15 simultaneous connections to the web service at any one given point. This means I will have to create a "thread manager" or if you want to call it a "queue manager" since I am not really using threads. Currently TheBrain.cfm page uses cfexecute to launch curl commands at the command line to launch the "simultaneous calls". Right now it launches 4 separate processes which means I have 4 simultaneous calls going on. My first thought was to have a call variable in the database which would be incremented when the execute calls the script and decremented when the called script is done making the call. This seems to be a little clunky and unreliable. The first thought is: What happens if for some reason the script does not decrement the call count... or if the call count doesn't get incremented then I could have more than 15 calls going on at once. I thought that an event gateway might be a way to handle this, but I do not know enough yet about those. I am not sure if I am going the right way about this or not that is why I am emailing a group. The main thing I need to accomplish is to make sure I do not have more than 15 simultaneous requests at 1 time. I think I need a queue manager of some sort. If you have any advice on how I should tackle this I would greatly appreciate it. Thanks!
