Welcome to eXamPLeS or eXample PLeaSe I’ve used curl at various times over the years. Yet I still have trouble remembering how to pass request headers. Sure my memory is getting worse, but the number of tools that we depend on keeps growing. Many we only use periodically, which means there is a non-zero switching cost when we have to relearn the exact options we need to pass and the specific format they have to be in.
