I need to find out what HTTP requests are made by composer install
This is because we're setting up some new servers at work, and have tightened security, making it necessary to whitelist all of the websites we want to be able to make outgoing requests to.
Is there a way to run composer install on my local machine, for instance, and capture what requests it is making when it does that?
Does it make separate requests to the packages on github (so we should whitelist github.com) - if yes, does it make requests to anywhere else?
